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.springframework</groupId>
          <artifactId>spring-test</artifactId>
          <version>5.0.2.RELEASE</version>
      </dependency>
      <dependency>
          <groupId>junit</groupId>
          <artifactId>junit</artifactId>
          <version>4.13</version>
          <scope>test</scope>
      </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.junit.Before;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.ApplicationContext;
import org.springframework.context.annotation.AnnotationConfigApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;
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<Words> all = wordsService.findAll();
        for (Words words : all) {
            System.out.println(words);
        }
    }
}
