Use version information

  • SpringBoot 2.7.3
  • springfox-boot-starter 3.0.0

Use the above version of the dependency package for integration, start the service, and directly report the previous error. It is preliminarily determined that the problem should be caused by the version.

Cause:

After springboot 2.6.0, the default path matching policy of spring MVC was changed from AntPathMatcher to PathPatternParser, resulting in an error in starting the service.

Solution:

Add the following line of configuration information to the application.properties configuration file to solve the problem

#How to Solve swagger error
spring.mvc.pathmatch.matching-strategy=ant_path_matcher

[Solved] Failed to configure a DataSource: ‘url‘ attribute is not specified and no embedded datasource could

An error occurred when starting the springboot server

Error prompt:

Description:

Failed to configure a DataSource: 'url' attribute is not specified and no embedded datasource could be configured.

Reason: Failed to determine a suitable driver class


Action:

Consider the following:
	If you want an embedded database (H2, HSQL or Derby), please put it on the classpath.
	If you have database settings to be loaded from a particular profile you may need to activate it (no profiles are currently active).

Solution:

This is a dependency issue, using druid’s data pool to configure the database parameters and not importing druid’s package in pom.xml.

<dependency>
<groupId>com.alibaba</groupId>
<artifactId>druid-spring-boot-starter</artifactId>
<version>1.1.23</version>
</dependency>

 

[Solved] JPA Create Sheet error at the First time: Cant DROP [xxx]；check that column/key exists

Main contents of error reporting information:

        Cant DROP [xxx]; check that column/key exists

Error reporting information reference data:

A configuration as follows:

package org.hibernate.tool.schema.internal;

public abstract class AbstractSchemaMigrator implements SchemaMigrator {
    …………

    private UniqueConstraintSchemaUpdateStrategy uniqueConstraintStrategy;
}

The reason for the locking problem is that the default configuration is: delete + first and then create.

Then the solution of the problem should consider using the second one: RECREATE_QUIETLY, try to create it directly and ignore the exception.

Problem-solving:

Configure the above mentioned configuration in application.yml, but since this configuration was not prompted, after a query, it was found in.

package org.hibernate.cfg;


public interface AvailableSettings extends org.hibernate.jpa.AvailableSettings {
    ……
    /*
        In most dialects, unique constraints are used for unique columns and unique keys. SchemaUpdate needs to create these constraints, but DB support for finding existing constraints is extremely inconsistent. In addition, non-explicitly named unique constraints use randomly generated characters. Therefore, choose from these strategies. org.hibernate.tool.hbm2ddl.UniqueConstraintSchemaUpdateStrategy.DROP_RECREATE_QUIETLY (default): Attempt to delete and then (re)create each unique constraint. Ignore any exceptions thrown. org.hibernate.tool.hbm2ddl.UniqueConstraintSchemaUpdateStrategy.RECREATE_QUIETLY : Attempts to (re)create the unique constraint, ignoring any exceptions thrown if the constraint already exists org.hibernate.tool. hbm2ddl.UniqueConstraintSchemaUpdateStrategy.SKIP : Don't try to create unique constraint structure updates
    */
    String UNIQUE_CONSTRAINT_SCHEMA_UPDATE_STRATEGY = "hibernate.schema_update.unique_constraint_strategy";

    ……
}

Configurate in application.yml:

spring:
  ## jpa configuration
  jpa:
    hibernate:
      ddl-auto: ${JPA_HIBERNATE_DDL_AUTO:update}
    open-in-view: ${JPA_OPEN_IN_VIEW:true}
    show-sql: ${JPA_SHOW_SQL:false}
    properties:
      hibernate:
        schema_update:
          ## This configuration is the focus of this blog post, after setting, the error report no longer appears
          unique_constraint_strategy: RECREATE_QUIETLY

[Solved] Feign Call Port Error: HttpMessageNotReadableException：JSON parse error：Illegal character ((CTRL-CHAR, code 31)

Background

In a timed task, the remote interface is called every hour for data synchronization. At first, the implementation method was to call the remote interface in a loop and pass in a single record each time, because each time we need to complete the operation of establishing a connection, data transfer, and disconnection, which is more expensive network and connection resources; later, after testing no problem, we changed to pass in a list for bulk operation after the loop is completed, and then the problem appeared.

10: 12:28.881 [http-nio-8200-exec-3] error c.y.c.s.h. globalexceptionhandler – [handleruntimeexception, 82] – Request Address’/doit ‘, unknown exception occurred org. springframework. http. converter.

Problem analysis

feign is configured as follows:

# feign
feign:
  sentinel:
    enabled: true
  okhttp:
    enabled: true
  httpclient:
    enabled: false
  client:
    config:
      default:
        connectTimeout: 10000
        readTimeout: 10000
  compression:
    request:
      enabled: true
    response:
      enabled: true

From the configuration, we can understand that the current configuration enables the request and response compression function. We know that when the compression is actually related to the size of the request body, if the requested data body itself is small, it can be transmitted directly without compression, which can save CPU resources for compression; there is a possible reason: compression is a threshold value, more than a certain threshold will be compressed. This can explain the previous question: why is it OK to transfer one piece of data at a time, but there is an error when transferring the list?

 

Solution:

Just turn compression off.

Note: Due to the change to bulk transfer, the business processing takes longer and errors like “Timed out…” may appear at the request initiation side. The configuration here changes the timeout of HTTP connection from 10s to 60s; when the data synchronization is finished, change it back.

[How to Solve] error at ::0 formal unbound in pointcut

error at ::0 formal unbound in pointcut

This error was reported when using aop’s @before for log prenotification

Error code here

	@Before(value = "webLogAspect()")
    public void logBefore(JoinPoint joinPoint，Object ret) {
        ServletRequestAttributes attributes = (ServletRequestAttributes) RequestContextHolder.getRequestAttributes();
        HttpServletRequest request = attributes.getRequest();
        //在attribute中加入开始时间
        request.setAttribute("time",System.currentTimeMillis());
    }

Then, after I remove the second parameter, it is normal

@Before(value = "webLogAspect()")
public void logBefore(JoinPoint joinPoint) {

Explain that other operations are required when multiple parameters are used, otherwise an error will be reported

@Before(value = "webLogAspect() && args(ret)")
public void logBefore(JoinPoint joinPoint, Object ret) {

[Solved] Tencent cloud SMS service error: FailedOperation.TemplateIncorrectOrUnapproved

1. Problem
an error occurs when sending a text message:

"Code":"FailedOperation.TemplateIncorrectOrUnapproved",
"Message":"template is not approved or request content does not match the approved template content"

2. Solution
the reason for the error is that the template content parameters are inconsistent with the set parameters. Set to consistent. As shown in the following figure, the template content has two parameters, so the templateparamset in the code should also set two parameters

    /* Template parameters: If no template parameters, set to empty */
    String[] templateParamSet = {"", "60"};
    req.setTemplateParamSet(templateParamSet);

[Solved] Springboot Error: swagger-UI/index.html Access Error 404

Springboot solves swagger UI/index HTML Access Error 404

Recently, I was working on a project to adopt swagger 3.0. After the project is started, access the swagger path: http://localhost:8880/vdmpess -web/swagger-ui/index. HTML reports 404 because webmvcconfig inherits webmvcconfigurationsupport. After inheriting this class, the relevant contents configured in the configuration file will become invalid and the static resource needs to be re specified
the swagger static resource needs to be re specified.

Swagger address in project

Solution:

Adds the address of the specified static resource

@Configuration
public class WebMvcConfig extends WebMvcConfigurationSupport {

    @Override
    public void addResourceHandlers(ResourceHandlerRegistry registry) {
        registry.
                addResourceHandler("/swagger-ui/**")
                .addResourceLocations("classpath:/META-INF/resources/webjars/springfox-swagger-ui/")
                .resourceChain(false);
    }

[Solved] Springboot uses redis to add LocaldateTime Java 8 error

To store an object in redis, you need to serialize the object. If a field is of localdatetime type, an error will appear

com.fasterxml.jackson.databind.exc.InvalidDefinitionException: Java 8 date/time type `java.time.LocalDateTime` not supported by default: add Module "com.fasterxml.jackson.datatype:jackson-datatype-jsr310" to enable handling (through reference chain: com.gd.base.vo.redis.RedisSysUser["Corresponding fields"])

The program needs to deserialize the data in redis. The deserializer I use here is the following:

@Configuration
@EnableCaching//Allow us to use the cache
public class RedisConfig {
    /**
     * Cache expiration time (seconds)
     */
    public static final long CACHE_EXPIRE_SECEND = 3600 * 2;

    @Bean // At this point, load our redisTemplate into the context of our spring, applicationContext
    public RedisTemplate<String,Object> redisTemplate(RedisConnectionFactory factory){
        //1. Initialize a redisTemplate
        RedisTemplate<String,Object> redisTemplate=new RedisTemplate<String,Object>();
        //2. Serial words (generally used for key values)
        RedisSerializer<String> redisSerializer=new StringRedisSerializer();
        //3. Introduce the json string conversion class (generally used for value processing)
        Jackson2JsonRedisSerializer jackson2JsonRedisSerializer=new Jackson2JsonRedisSerializer(Object.class);
        ObjectMapper objectMapper=new ObjectMapper();
        //3.1 Set the access rights of objectMapper
        objectMapper.setVisibility(PropertyAccessor.ALL, JsonAutoDetect.Visibility.ANY);
        //3.2 Specify the serialized input type, that is, store the data in the database to the redis cache according to certain types.
        </objectMapper.enableDefaultTyping(ObjectMapper.DefaultTyping.NON_FINAL);// Recently upgraded SpringBoot, found that enableDefaultTyping method expired. You can use the following method instead
        objectMapper.activateDefaultTyping(LaissezFaireSubTypeValidator.instance,ObjectMapper.DefaultTyping.NON_FINAL, JsonTypeInfo.As. WRAPPER_ARRAY);
        jackson2JsonRedisSerializer.setObjectMapper(objectMapper);
        //4. Create the link
        redisTemplate.setConnectionFactory(factory);
        //4.1 redis key value serialization
        redisTemplate.setKeySerializer(redisSerializer);
        //4.2 value serialization, because most of our values are converted through objects, so use jackson2JsonRedisSerializer
        redisTemplate.setValueSerializer(jackson2JsonRedisSerializer);
        // 4.3 Serialization of value, serialization of hashmap
        redisTemplate.setHashValueSerializer(jackson2JsonRedisSerializer);
        return redisTemplate;
    }

    @Bean
    public CacheManager cacheManager(RedisConnectionFactory factory){
        // 1. Serial words (generally used for key values)
        RedisSerializer<String> redisSerializer=new StringRedisSerializer();
        //2. Introduce the json string conversion class (generally used for value processing)
        Jackson2JsonRedisSerializer jackson2JsonRedisSerializer=new Jackson2JsonRedisSerializer(Object.class);
        ObjectMapper objectMapper=new ObjectMapper();
        //2.1 Set the access rights of objectMapper
        objectMapper.setVisibility(PropertyAccessor.ALL, JsonAutoDetect.Visibility.ANY);
        //2.2 Specify the serialized input type, that is, store the data in the database to the redis cache according to a certain type.
        </objectMapper.enableDefaultTyping(ObjectMapper.DefaultTyping.NON_FINAL);// Recently upgraded SpringBoot, found that enableDefaultTyping method expired. You can use the following method instead
        objectMapper.activateDefaultTyping(LaissezFaireSubTypeValidator.instance,ObjectMapper.DefaultTyping.NON_FINAL, JsonTypeInfo.As. WRAPPER_ARRAY);
        jackson2JsonRedisSerializer.setObjectMapper(objectMapper);
        //3. Serialization configuration, garbled problem solving and timeliness of our cache
        RedisCacheConfiguration config=RedisCacheConfiguration.defaultCacheConfig().
                entryTtl(Duration.ofSeconds(CACHE_EXPIRE_SECEND)). // Cache timeliness setting
                serializeKeysWith(RedisSerializationContext.SerializationPair.fromSerializer(redisSerializer)). //key serialization
                serializeValuesWith(RedisSerializationContext.SerializationPair.fromSerializer(jackson2JsonRedisSerializer)). //value serialization
                disableCachingNullValues();//null values are not stored in the cache
        //4. Create the cacheManager link and set the properties
        RedisCacheManager cacheManager= RedisCacheManager.builder(factory).cacheDefaults(config).build();
        return cacheManager;
    }

}

Processing error reports:
① add comments to the corresponding fields

    @JsonFormat(pattern = "yyyy-MM-dd HH:mm:ss")
    @JsonDeserialize(using = LocalDateTimeDeserializer.class)
    @JsonSerialize(using = LocalDateTimeSerializer.class)

The error report is gone

If you are sure that there is no problem with your parameters, it is likely that the problem lies in your @requestbody AAA a
the problem I encounter here is that protobuf is used, but no corresponding bean is injected, resulting in an error. Just add the following code to the application:

PS: protobufmodule is our own extended com fasterxml.jackson.databind.Module class, it’s inconvenient to put it out. You can consult the data by yourself

    @Bean
    ProtobufJsonFormatHttpMessageConverter protobufHttpMessageConverter() {
        return new  ProtobufJsonFormatHttpMessageConverter();
    }

    @Bean
    public Jackson2ObjectMapperBuilderCustomizer jsonCustomizer() {
        return builder -> builder.serializationInclusion(JsonInclude.Include.NON_NULL)
                .modules(new ProtobufModule(), new JavaTimeModule());
    }
