Spring整合Junit的配置

• 导入Spring整合Junit的jar包，Junit必须在4.11版本以上

  <dependencies>
      <dependency>
          <groupId>org.springframeworkgroupId>
          <artifactId>spring-testartifactId>
          <version>5.0.2.RELEASEversion>
      dependency>
      <dependency>
          <groupId>junitgroupId>
          <artifactId>junitartifactId>
          <version>4.13version>
          <scope>testscope>
      dependency>
  dependencies>

• 使用Junit提供的注解把原有的main方法替换成spring提供的main方法@RunWith(SpringJUnit4ClassRunner.class)

• 告知spring运行器，spring和ioc创建是基于xml配置还是注解配置，并且说明位置。@ContextConfiguration

  • 属性：location指定xml文件的位置，加上classpath，标识在类路径下；classes指定注解类所在的位置

package com.mypro.test;
?
import com.mypro.entity.Words;
import com.mypro.service.WordsService;
import com.mypro.service.impl.WordsServiceImpl;
import config.SpringConfiguration;

import org.springframework.test.context.ContextConfiguration;
import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;

import java.util.Date;
import java.util.List;
?
@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(classes = SpringConfiguration.class)
public class WordsServiceTest {
    // 完成以上步骤才可以自动注入
    @Autowired
    private WordsService wordsService;
?
    @Test
    public void testFindAll(){
        List all = wordsService.findAll();
        for (Words words : all) {
            System.out.println(words);
        }
    }
}
