The reason is that the import annotation calls a parameterless constructor, while my user class does not have a parameterless constructor, so an error is reported.
Problem solved after adding.

Through the error message, it is judged that it is caused by a spring bean, but my project does not reference spring at all. It is suspected that it is caused by jar package conflict
Solution:
If Druid’s jar package is referenced in your project, it’s probably the problem. Upgrade the Druid jar package or downgrade the version of the Druid jar package in the project. We are from druid-1.0.10 upgrade to druid-1.0.3 problem solving. Druid’s jar package download address is attached.

How to Solve Springboot use thymeleaf template error
When using the thymeleaf template for the first time, the following error is reported when starting:
The following method did not exist:
org.thymeleaf.spring5.SpringTemplateEngine.setRenderHiddenMarkersBeforeCheckboxes(Z)V
The reason for this error is that the version of springboot is incompatible with the version of thymeleaf template. Add the following content to the <properties> tag:
<thymeleaf-spring5.version>3.0.9.RELEASE</thymeleaf-spring5.version>
<thymeleaf-layout-dialect.version>2.2.2</thymeleaf-layout-dialect.version>
After adding, you can start springboot
BigDecimal Error: NumberFormatException [How to Solve]
Question:
1. This problem occurs first because it is not handled properly during type conversion, and non null judgment is required
Solution:
String val =””；
if (val!=null && !val.equals("")){
merchantDetailData.setTransactionAmount(new BigDecimal(StringUtils.nvl(list.get(9))));
}
Only when the judgment value is not equal to null and not equal to “”

... 33 moreCheck some big guys’ articles until the problem is called: injection bean failure exception.
After checking, it is found that it is caused by the inconsistent version of the jar package. The version of spring I use is 5.3 13. Before, in order to save trouble, we directly copied other people’s core jar package, and its version was 5.2 6. I changed the versions of these four jar packages to 5.3.0, which is consistent with the spring version 13. The problem is solved
Modified jar package:
There is also a small problem. When using the pointcut expression, there must be a space between * and the following com, otherwise an error will be reported
@Before(value = "execution(* com.testAop.anno.User.add(..))")
[Solved] BeanCreationNotAllowedException Error: Error creating bean with name ‘rabbitConnectionFactory‘
org.springframework.beans.factory.BeanCreationNotAllowedException:
Error creating bean with name ‘rabbitConnectionFactory’:
Singleton bean creation not allowed while singletons of this factory are in destruction (Do not request a bean from a BeanFactory in a destroy method implementation!)
Once the project reports this error, in most cases, the sub paths in the control layer are repeated, and non unique channels appear during compilation, as shown below
After copying, the sub path of the control layer access path has been changed accordingly

[Solved] org.springframework.beans.factory.BeanCreationException: Error creating bean with name ‘xxx‘
1. Problem description
org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'org.springframework.aop.config.internalAutoProxyCreator': Initialization of bean failed; nested exception is java.lang.NoClassDefFoundError: org/aspectj/lang/annotation/Around
2. Anomaly analysis
org. springframework. beans. factory. BeanCreationException: Error creating bean with name ‘XXX’
This exception is: bean injection failure exception. If this exception occurs, the corresponding bean cannot be found! The reasons for bean injection failure include but are not limited to the following:
The corresponding bean is not annotated; There is an error adding annotation to the corresponding bean, for example, the @service of spring is incorrectly selected as Dubbo; Select the wrong automatic injection method, etc.
Caused by: java.lang.ClassNotFoundException: org.aspectj.lang.annotation. Around

[Solved] Error creating bean with name ‘fileVisitController‘ defined in file
When importing the jar package from nexus into the local project, an error occurred during startup:
org.springframework.beans.factory.BeanCreationException: Error creating bean with name
'fileVisitController' defined in file [D:\dengkun\dengkun_server\dengkun-
api\target\classes\com\dengkun\api\controller\auxiliary\FileVisitController.class]:
Instantiation of bean failed; nested exception is
org.springframework.beans.BeanInstantiationException: Failed to instantiate
[com.dengkun.api.controller.auxiliary.FileVisitController]: Constructor threw exception;
nested exception is org.apache.ibatis.binding.BindingException: Type interface
com.dengkun.dao.FileVisitMapper is not known to the MapperRegistry.
After troubleshooting, it is found that the mybatis-conf.xml file in the jar package has the same name as the XML file in other jar packages;
So, change mybatis-conf.xml to mybatis-conf-lct.xml The XML program can start normally
[Solved] Websocket Error: WebSocket is already in CLOSING or CLOSED state
When the front-end project communicates with the back-end Java websocket for a long time, sometimes the browser will report an error
WebSocket is already in CLOSING or CLOSED state.
This problem may be caused by the data length passed by websocket being greater than 8192 After websocket establishes a connection, the length of JSON passed should be & lt= 8192, otherwise an error will be reported Websocket is already in closing or closed state.
1. At this point, we can add some code in web.xml to limit the parameter length limit in websocket.
# Limit WebSocket pass data size to 50M <context-param> <param-name>org.apache.tomcat.websocket.textBufferSize</param-name> <param-value>5242800</param-value> </context-param> <context-param> <param-name>org.apache.tomcat.websocket.binaryBufferSize</param-name> <param-value>5242800</param-value> </context-param>
After adding the above code, you can modify the size and length of the transfer parameters of websocket, which is limited to 50m.
2. The above method is not available for the springboot project because there is no web.xml file in the project directory. At this time, we can put the following code into the springboot project under the context directory of the project (or create a new code class or block at will)
import org.springframework.boot.autoconfigure.EnableAutoConfiguration;
import org.springframework.boot.web.servlet.ServletContextInitializer;
import org.springframework.context.annotation.ComponentScan;
import org.springframework.context.annotation.Configuration;
import org.springframework.web.util.WebAppRootListener;
import javax.servlet.ServletContext;
import javax.servlet.ServletException;
/**
* Add WebSocket pass data size limit of 50M
*/
@Configuration
@ComponentScan
@EnableAutoConfiguration
public class WebSocketConfig implements ServletContextInitializer {
//Configure websocket transfer size, 50M
@Override
public void onStartup(ServletContext servletContext) throws ServletException {
servletContext.addListener(WebAppRootListener.class);
servletContext.setInitParameter("org.apache.tomcat.websocket.textBufferSize","52428800");
servletContext.setInitParameter("org.apache.tomcat.websocket.binaryBufferSize","52428800");
}
}The above code can solve the problem of websocket is already in closing or closed state
You can successfully modify the size limit of websocket transmission data to 50m.
Note: a problem was found during use. If the above configuration is started with the built-in Tomcat in springboot, there is no problem, but the operation using the external Tomcat after war does not take effect. Finally, it is found that the problem is due to the external Tomcat version. The problem version is tomcat8.0.xx, but there is no problem using tomcat8.5.xx
