Solution: The introduction of both Mybatis and Mybatis-plus into the dependency will cause a conflict, either one. In addition to noticing if there is a conflict in the pom file of this module, we also need to see if the parent module of this module has already introduced the mybaits dependency and you later introduce the Mybatis-plus module in this module, causing a conflict. This scenario is more insidious and not easy to detect.

[Solved] Springboot Package jar and Startup Error: It was loaded from the following location

Previously, when using springboot to develop the system, the @Resouse annotation was used. There was no exception during the idea runtime, but the jar package conflict was reported when the deployment was packaged.

09:07:51.234 [main] ERROR o.s.b.d.LoggingFailureAnalysisReporter - [report,40] - 

***************************
APPLICATION FAILED TO START
***************************

Description:

An attempt was made to call a method that does not exist. The attempt was made from the following location:

    org.springframework.context.annotation.CommonAnnotationBeanPostProcessor$ResourceElement.<init>(CommonAnnotationBeanPostProcessor.java:664)

The following method did not exist:

    'java.lang.String javax.annotation.Resource.lookup()'

The method's class, javax.annotation.Resource, is available from the following locations:

    jar:file:/C:/vic/vic-admin.jar!/BOOT-INF/lib/jsr250-api-1.0.jar!/javax/annotation/Resource.class
    jar:file:/C:/vic/vic-admin.jar!/BOOT-INF/lib/jakarta.annotation-api-1.3.5.jar!/javax/annotation/Resource.class

The class hierarchy was loaded from the following locations:

    javax.annotation.Resource: jar:file:/C:/vic/vic-admin.jar!/BOOT-INF/lib/jsr250-api-1.0.jar!/


Action:

Correct the classpath of your application so that it contains a single, compatible version of javax.annotation.Resource

Reason:

jsr250-api-1.0.jar and jakarta.annotation-api-1.3.5.jar are duplicated

Solution:

Import the following dependency in the pom of Maven. the codes is as below:

<dependency>
    <groupId>javax.annotation</groupId>
    <artifactId>javax.annotation-api</artifactId>
    <version>1.3.2</version>
</dependency>

The purpose of this is to make the system automatically import the latest jar package

[Solved] SpringBoot Startup Error: Unable to start LiveReload server

WARN 12000 — [ restartedMain] o.s.b.d.a.OptionalLiveReloadServer : Unable to start LiveReload server

Cause of problem: solution:

problem

0000-00-00 00:00:55.497  WARN 12000 --- [  restartedMain] o.s.b.d.a.OptionalLiveReloadServer       : Unable to start LiveReload server

reason:

When you use the springboot hot deployment plug-in devtools , and start multiple applications at the same time, the console will report this warning;

The problem is that a port is configured in devtoolsproperties. The default is 35729

       public static class Livereload {
                private boolean enabled = true;

                private int port = 35729;

        ... }

Multiple ports are in conflict, causing the hot deployment plug-in behind to not take effect.

Solution:

Add the following configuration to the application.properties file:

spring. Devtools. Livereload. Port = 35731 (specified port does not duplicate port)

2. Solution

Authentication see error prompt

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).

 

The error may be due to the lack of configuration database related information. If the project does not need to configure the database, you can add it to the startup class:

(exclude = {DataSourceAutoConfiguration.class, HibernateJpaAutoConfiguration.class})

 

 perfect!

[Solved] Springboot Startup Error: Consider defining a bean of type ‘XXX’ in your configuration.

1 Reply

I. Introduction:

The project was built using springboot automatic injection, but an error was reported when it started! ! ! , The error is as shown below:

Description: Field userEntityMapper in com.xxx.xxx.service.UserService required a bean of

 type'com.xxx.xxx.dao.UserEntityMapper' that could not be found.
 
Action: Consider defining a bean of

 type'com.xxx.xxx .dao.UserEntityMapper' in your configuration.

2. Solution:

1. Check whether the annotations you wrote are wrong, and not.

2. Find solutions on the Internet: as follows:

step one:

　　Add in the configuration file of springboot, the configuration of mybatis is as follows:

mybatis: 
  typeAliasesPackage: com.xxx.xxx.dao.entity 
  mapperLocations: classpath:mapper/*.xml

 Step two:

　　① Put the interface and the corresponding implementation class in the same directory or its subdirectory as the application startup class , so that the annotations can be scanned, which is the most trouble-free way. (Not tested)
　　② Or add @MapperScan or @ComponentScan annotations to the startup class , and manually specify the annotations under which packages the application class should scan, as shown below: 

@SpringBootApplication
 @ComponentScan(basePackages = {"com.xxx.xxx.dao"})

③Or add @Mapper annotation 　　on the interface .

@Mapper
 public  interface UserMapper { 
}

ps: The reason why the corresponding Bean was not found is because @SpringBootApplication did not scan it.

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).


Process finished with exit code 1

 

the reason

The application does not use DataSource, but introduces mybatis-spring-boot-starter in pom.xml

 

Problem solution

There are two types:
remove the dependency of mybatis-spring-boot-starter, so that it will not trigger the spring boot related
code 　　 disable the spring boot automatically initialize the DataSource related code

There are two ways to prohibit:

In the @SpringBootApplication of the startup class, add

@SpringBootApplication(exclude = { DataSourceAutoConfiguration.class,DataSourceTransactionManagerAutoConfiguration.class })

 

Configure in application.properties:

spring.autoconfigure.exclude=org.springframework.boot.autoconfigure.jdbc.DataSourceAutoConfiguration,org.springframework.boot.autoconfigure.jdbc.DataSourceTransactionManagerAutoConfiguration

 

Get it done!

An error is reported when springboot starts: error creating bean with name ‘XXXX’

Error creating bean with name ‘XXXX’

The complete errors are as follows: Cause Analysis:

The complete error report is as follows:

 Exception encountered during context initialization - cancelling refresh attempt: 
 org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 
 'testHelloController': Unsatisfied dependency expressed through field 'testHelloService'; nested exception is 
 org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type 
 'com.jun.service.test.TestHelloService' available: expected at least 1 bean which qualifies as autowire 
 candidate. Dependency annotations: 
 {@org.springframework.beans.factory.annotation.Autowired(required=true)}

Cause analysis:

Because I’m a beginner of springboot, I just want to let the project run first to see the effect. If it takes half a day to build the project structure completely, I will report such a mistake as soon as I start it. The reason is very clear, that is, I can’t find the testhelloservice object template to inject it when I start it, and then I look at the @ service annotation in the service layer. It’s very smart When spring boot is started, it does not scan the service layer. After looking at the data, if so, you can directly type a annotation @ componentscan in the application of spring boot startup class to solve this problem:
the following is the code before error reporting:

package com.jun.web.test;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

@SpringBootApplication
