在尝试运行Spring Boot JPA测试代码时遇到了'Failed to load ApplicationContext'错误。经过排查，发现错误与JDK版本、POM配置以及数据源设置有关。通过将JDK版本从13降低到12-8，排除DataSourceAutoConfiguration，以及调整@SpringBootApplication注解，成功解决了问题，测试通过。

application.properties
spring.datasource.driverClassName=com.mysql.jdbc.Driver
spring.datasource.url=jdbc:mysql://139.23.01.23:3306/card
spring.datasource.username=AAA
spring.datasource.password=BBB@
spring.datasource.type=com.alibaba.druid.pool.DruidDataSource
spring.jpa.hibernate.ddl-auto=update
spring.jpa.show-sql=true

关于测试代码报错

package mm;

import mm.App;
import mm.entry.User;
import mm.entry.UserDao;

import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.autoconfigure.EnableAutoConfiguration;
import org.springframework.boot.autoconfigure.jdbc.DataSourceAutoConfiguration;
import org.springframework.boot.test.context.SpringBootTest;
import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;
import org.springframework.test.context.junit4.SpringRunner;

//@EnableAutoConfiguration(exclude={DataSourceAutoConfiguration.class})
//@RunWith(SpringRunner.class)
//报错情况：application.properties Failed to load ApplicationContext
// 上述两注解更改无效，后改JDK版本从13 改到12–8 ，一切正常，测试通过
@RunWith(SpringJUnit4ClassRunner.class)

@SpringBootTest(classes = App.class )
public class mtest {
@Autowired
private UserDao muser;

@Test
public void testadd()
{
User ent = new User();
ent.setName(“anejijsk09”);
ent.setPhone(“13956565”);
ent.setEmail(“163.com”);
