How to Solve:Failed to execute goal org.codehaus.mojo:exec-maven-plugin:3.0.0:exec (default-cli) on project spring_aop: Command execution failed.error

error:

Failed to execute goal org.codehaus.mojo:exec-maven-plugin:3.0.0:exec (default-cli) on project 
spring_aop: Command execution failed.

Solution 1: in this case, I will use the main method to execute the program and use the unit test @ test instead

~It used to be like this: running with main

public class MyTest {
    public static void main(String[] args) {
    
        ClassPathXmlApplicationContext context = new ClassPathXmlApplicationContext("applicationContext.xml");

        //Dynamic proxies represent interfaces
        UserService userservice = (UserService) context.getBean("userservice");

        userservice.add();
    }
}

~Changed to: use @ test

import com.niuyun.service.UserService;
import com.niuyun.service.UserServiceImpl;
import org.junit.Test;
import org.springframework.context.support.ClassPathXmlApplicationContext;

public class MyTest {

    @Test
    public void test(){
        ClassPathXmlApplicationContext context = new ClassPathXmlApplicationContext("applicationContext.xml");

        //Dynamic proxies represent interfaces
        UserService userservice = (UserService) context.getBean("userservice");

        userservice.add();
    }
}

! Expansion

@Test is the basis of JUnit testing, and its functions are as follows:
1. Specify the type of exception to be thrown
2. Test the running time of the code.

Solution 2: if you have to use the main function, you can introduce two plug-ins in Maven (compiler can not be introduced), but it may lead to Chinese garbled.

Maven compiler plugin: used to compile java files, specify JDK version, etc.
exec Maven plugin: used to execute class files, in which the path of executing class should be indicated in plug-in configuration.

Solve the problem of garbled code

Method 1:
in setting – & gt; maven-> Runner-> Fill in the column VM options
with – dfile. Encoding = GB2312

Method 2: add in pom.xml (I tried this method, but I didn’t solve the garbled code, which may be useful to you)

<properties>
	<!-- Encoding when copying files -->
	<project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
	<project.reporting.outputEncoding>UTF-8</project.reporting.outputEncoding>
	<!-- Compile-time coding -->
    <maven.compiler.encoding>UTF-8</maven.compiler.encoding>
</properties>
