测试类

1. 需要加上2个注解：
@RunWith(SpringRunner.class)
@SpringBootTest(classes = Application.class)

2. 自动装配 CategoryDAO dao; 以便于使用

3. test 方法加上 @Test 注解，然后就可以使用dao来工作了

4. 运行的时候选择 JUnit Test 方式

package com.how2java.springboot.test;   import java.util.List;   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; import com.how2java.springboot.Application; import com.how2java.springboot.dao.CategoryDAO; import com.how2java.springboot.pojo.Category;   @RunWith(SpringRunner.class) @SpringBootTest(classes = Application.class) public class TestJPA {       @Autowired CategoryDAO dao;           @Test     public void test() {         List<Category> cs=  dao.findAll();         for (Category c : cs) {             System.out.println("c.getName():"+ c.getName());         }               } }

 步骤 7 : 

测试

运行 TestJPA 就可以看到如图所示的效果了
