Spring boot test测试中@Autowired不起作用 报空指针异常

测试代码如下：

?

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15

import org.junit.Test; import org.junit.runner.RunWith; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.boot.test.context.SpringBootTest; import org.springframework.test.context.junit4.SpringRunner;    public class MoveSysUserTest {     @Autowired     private MoveSysUser moveSysUser;        @Test     public void testMoveSysUser() {         boolean res = moveSysUser.moveSysUser();         System.out.println(res);     }

此时运行，会提示moveSysUser为空，报空指针异常

解决方法：

1、添加注解

?

1 2	@RunWith(SpringRunner.class) @SpringBootTest

 

?

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18

import org.junit.Test; import org.junit.runner.RunWith; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.boot.test.context.SpringBootTest; import org.springframework.test.context.junit4.SpringRunner;    @RunWith(SpringRunner.class) @SpringBootTest public class MoveSysUserTest {     @Autowired     private MoveSysUser moveSysUser;        @Test     public void testMoveSysUser() {         boolean res = moveSysUser.moveSysUser();         System.out.println(res);     } }

　　

　　

 

 

　注：如果@RunWith 飘红则需要在pom文件添加junit依赖并且把Test注解使用junit

?

1 2 3 4 5 6

<dependency>             <groupId>junit</groupId>             <artifactId>junit</artifactId>             <scope>test</scope>             <version>4.12</version>         </dependency>

　　

2、继承一个带有这个注解的类
