java.lang.AbstractMethodError: Receiver class com.alibaba.cloud.sentinel.feign.SentinelContractHolde

Caused by: java.lang.AbstractMethodError: Receiver class com.alibaba.cloud.sentinel.feign.SentinelContractHolder does not define or inherit an implementation of the resolved method abstract parseAndValidatateMetadata(Ljava/lang/Class;) Ljava/util/List; of interface feign.Contract.

When doing openfeign for sentinel service, I encountered the following errors:

according to the source code tracing, I found that there was a problem with the implementation class of feign’s contract interface. In my project springcloud, Sr1 version h, depends on the following:

the reason for the problem is that the version is inconsistent. For feign’s contract interface, 2.2.1 and 2.2.2 are different
2.2.1.RELEASE：

// TODO: break this and correct spelling at some point
List<MethodMetadata> parseAndValidatateMetadata(Class<?> targetType);

2.2.2.RELEASE：

List<MethodMetadata> parseAndValidateMetadata(Class<?> targetType);

In 2.2.1.release, there is a line of comment description. The spelling of interface method name is wrong. In 2.2.2.release, the method name has been corrected, that is, the method name has changed
the sentinelcontractholder class in spring cloud Alibaba sentinel uses this method of the interface (feign 2.2.1. Release version)


```java
@Override
public List<MethodMetadata> parseAndValidatateMetadata(Class<?> targetType) {
	List<MethodMetadata> metadatas = delegate.parseAndValidatateMetadata(targetType);
	metadatas.forEach(metadata -> METADATA_MAP
			.put(targetType.getName() + metadata.configKey(), metadata));
	return metadatas;
}

After finding out the reason, modify the implementation class of contract interface of feign. Create a package of com.alibaba.cloud.sentinel.feign in the appropriate place of the project. Modify the implementation class sentinelcontractholder as follows:

/**
 * @author geng
 * @create 2021/4/30 -- 10:47
 */
public class SentinelContractHolder implements Contract {
    private final Contract delegate;

    /**
     * map key is constructed by ClassFullName + configKey. configKey is constructed by
     * {@link feign.Feign#configKey}
     */
    public final static Map<String, MethodMetadata> METADATA_MAP = new HashMap<>();

    public SentinelContractHolder(Contract delegate) {
        this.delegate = delegate;
    }

    @Override
    public List<MethodMetadata> parseAndValidateMetadata(Class<?> targetType) {
        List<MethodMetadata> metadatas = delegate.parseAndValidateMetadata(targetType);
        metadatas.forEach(metadata -> METADATA_MAP
                .put(targetType.getName() + metadata.configKey(), metadata));
        return metadatas;
    }
}

Run again, start successfully!

How to Solve Spring Cloud Error context has been closed already

Context has been closed already solution

Error code

With such a piece of code, the context has been closed already error may occur during running, and once it occurs, it will make an error every time it runs in the future.

@Component
public class SpringContextUtil implements ApplicationContextAware {

    private static ApplicationContext context = null;

    @Override
    public void setApplicationContext(ApplicationContext applicationContext) throws BeansException {
        ApplicationContextExt.context = applicationContext;
    }

	/**
	 * This static method allows you to retrieve the desired bean from the Spring context.
	 */
	public static <T> T getBean(Class<T> cls) {
        if (context == null)
            throw new IllegalStateException("no application context aviliable.");
        try {
            return (T) context.getBean(cls); // Wrong!
        } catch (BeansException e) {
			throw new RuntimeException(e);
        }
        return (T) null;
    }
}

Cause analysis

However, when spring cloud context. Jar is included in the classpath, because the contextrefresher class will close the old context when the context is refreshed, so that the context in the static class has been closed, so this error will occur.

Trigger exploration

Find out the direct reason. Find out that a jar that you depend on listens to a notification from MQ. When you hear the message to be refreshed, you will refresh the context, which leads to this phenomenon.

Failed to configure a DataSource

When using spring cloud, we first create a parent project, and then add Eureka server module and SMS module, which run normally. Finally, after adding the payment module (mybatis and MySQL need to be integrated), the Eureka server module and SMS module report an error:

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).

After investigation, because mybatis jar package is introduced:

<dependency>
            <groupId>org.mybatis.spring.boot</groupId>
            <artifactId>mybatis-spring-boot-starter</artifactId>
            <version>1.3.1</version>
</dependency>

Spring boot will load by default org.springframework.boot . autoconfigure.jdbc.DataSourceAutoConfiguration and the datasourceautoconfiguration class uses the @ configuration annotation to inject datasource into spring Bean, and because there is no configuration information about datasource in the project (Eureka server module and SMS module), when spring creates datasource bean, it will report an error due to lack of relevant information.

terms of settlement:

1. Add exclude to the @ springbootapplication annotation to release the automatic loading of datasourceautoconfiguration.

@EnableEurekaServer
@SpringBootApplication(exclude = DataSourceAutoConfiguration.class)
public class EurekaServerApplication {

	public static void main(String[] args) {
		SpringApplication.run(EurekaServerApplication.class, args);
	}
}

2. In the pom.xml The common jar dependencies of all sub modules are stored in the file, and the non common dependencies are stored in the file of each module itself pom.xml It is stated in the document. The advantage of this method is that the dependence of each module will not interfere with each other.

Spring cloud Alibaba 2020.0.rc1 does not integrate ribbon error reporting unknownhostexception

The title starts from 3 because other pits have been recorded before

3. Spring cloud Alibaba 2020.0.rc1 does not integrate ribbon error reporting unknownhostexception

3.1 first check whether our notes are correct, and then look at the following

3.2 no ribbon

We can see from the dependency package that spring cloud Alibaba 2020.0.rc1 is not integrated with ribbon, which is not right,

In this version, calling the microservice through resttemplate always prompts that the microservice is not found

3.3 it’s OK to go back to 2.1.4 or manually add the ribbon dependency

When I go back to 2.1.4.release and look at dependency, there is ribbon

The visit is normal

Join ribbon manually

It’s OK, too

Although I don’t know whether to give up the ribbon or forget to add it, I haven’t found any other method and usage to record the time 2021.3.22

The client can’t be registered in Eureka. After looking around, we found that spring boot starter web is missing in the client POM file, plus

Integration openfeign failed to start

Using the open feign development interface, the direct startup fails, and the following exception is thrown:

nested exception is java.lang.IllegalStateException: No Feign Client for loadBalancing defined. Did you forget to include spring-cloud-starter-loadbalancer?

The problem is obviously that spring cloud starter loadbalancer is not added, so in the pom.xml Add the following dependencies to:

<dependency>
    <groupId>org.springframework.cloud</groupId>
    <artifactId>spring-cloud-loadbalancer</artifactId>
</dependency>

After re importing the dependency, it starts successfully, but the calling interface still reports an error:

java.lang.AbstractMethodError: org.springframework.cloud.netflix.ribbon.RibbonLoadBalancerClient.choose(Ljava/lang/String;Lorg/springframework/cloud/client/loadbalancer/Request;)Lorg/springframework/cloud/client/ServiceInstance;

This is because spring cloud replaces the load balancing component from ribbon to loadbalancer. You need to exclude the ribbon component in spring cloud starter Alibaba Nacos discovery, otherwise loadbalancer will not work.

<dependency>
    <groupId>com.alibaba.cloud</groupId>
    <artifactId>spring-cloud-starter-alibaba-nacos-discovery</artifactId>

About content type ‘multipart / form data…’ not support

Project Scenario:
on using springcloud, the gateway jump specifies that the service displays an error message

Problem description:

Content type 'multipart/form-data;boundary=----WebKitFormBoundaryek7Ljn5odm2QALlC;charset=UTF-8' not supported

Reason analysis:
this is because the requested parameter is content-type:multipart/form-data, which is submitted as a form. Therefore, the problem occurs on the parameter, and the annotation on the parameter can be removed (it only needs to be in the parameter form of springmvc)

Error when connecting to database: DB2 SQL error: sqlcode = – 204, sqlstate = 42704, sqlerrmc= YXUAT.CUST_ BLK_ REL, DRIVER=4.25.13

DB2 SQL Error: SQLCODE=-204, SQLSTATE=42704, SQLERRMC= yxuat. CUST_BLK_REL, DRIVER=4.25.13

Reason: When using MyBATIS, the remote database was connected, and the login user did not specify which schemas to use, that is, the user name was not specified. This led to the fact that Mybaits could not find the schemas we wanted, so it reported an error.
Solution 1: When you write SQL statements, you simply add schemas before the table names in the SQL
For example: SELECT * from cmis_uat1.cust_blk_rel
Solution 2: Add schemas when configuring datasource.
For example: spring: a datasource: url: JDBC: db2:// 10.10.0.36:50000/HNCKC: currentSchema = CMIS_UAT1; username: yxuat password: xfjr2016

Spring cloud is a big hole. Failed to start bean ‘eurekaAutoServiceRegistration’

just to make it clear. When I was working on cloud consumption service (I did not do it, but I was responsible for changing it, because we used 1.5.4 distribution version of boot, and then cloud and boot version were different, and a solution package was introduced, and finally I changed it back, so it could not be started.) , directly in the spring boot normal, and then thrown into tomcat to report an error, error log is as follows 

17:06:17.556 logback [localhost-startStop-1] ERROR o.s.boot.SpringApplication - Application startup failed

and I searched baidu but did not find a solution. Finally, I found a similar problem with Google in over the wall, but I could not start it directly. The solution is to add a class
but have no effect 

package com.netwit.questionbank;

import org.springframework.beans.BeansException;
import org.springframework.beans.factory.config.BeanDefinition;
import org.springframework.beans.factory.config.BeanFactoryPostProcessor;
import org.springframework.beans.factory.config.ConfigurableListableBeanFactory;
import org.springframework.stereotype.Component;

import java.util.Arrays;

@Component
public abstract class FeignBeanFactoryPostProcessor implements BeanFactoryPostProcessor {
    @Override
    public void postProcessBeanFactory(ConfigurableListableBeanFactory beanFactory) throws BeansException {
        if (containsBeanDefinition(beanFactory, "feignContext", "eurekaAutoServiceRegistration")) {
            BeanDefinition bd = beanFactory.getBeanDefinition("feignContext");
            bd.setDependsOn("eurekaAutoServiceRegistration");
        }
    }

    private boolean containsBeanDefinition(ConfigurableListableBeanFactory beanFactory, String... beans) {
        return Arrays.stream(beans).allMatch(b -> beanFactory.containsBeanDefinition(b));
    }
}

can’t be solved after many tests, so I have to test one by one.
finally comment out these two packages see the blue sky 

<dependency>
			<groupId>xpp3</groupId>
			<artifactId>xpp3_min</artifactId>
			<version>1.1.4c</version>
		</dependency>
		<dependency>
			<groupId>com.thoughtworks.xstream</groupId>
			<artifactId>xstream</artifactId>
			<version>1.4.9</version>
		</dependency>

in addition to do an important complement, appear this kind of circumstance is another possibility tomcat activated twice,
why start twice, because I inherited two SpringBootServletInitializer


It’s

and you just take one out of it
