Java Config 下的Spring Test方式-优快云博客

本文介绍了使用Java Spring框架进行应用开发的过程，包括手动获取bean、使用spring-test注解和Mockito进行单元测试的方法，强调了Spring框架在简化依赖管理和提高开发效率方面的优势。

用了三种方式：
1.纯手动取bean：

package com.wang.test;

import com.marsmother.commission.core.config.MapperConfig;
import com.marsmother.commission.core.config.PropertyConfig;
import com.marsmother.commission.core.config.ServiceConfig;
import com.marsmother.commission.core.dto.GeneralResponseData;
import com.marsmother.commission.core.service.UserService;
import com.marsmother.commission.site.config.SecurityConfig;
import org.junit.Before;
import org.junit.Test;
import org.springframework.context.annotation.AnnotationConfigApplicationContext;

/**
 * Created by Wanglei on 15/10/29.
 */
public class CustomeTest {

    private static AnnotationConfigApplicationContext context = new AnnotationConfigApplicationContext();

    @Before
    public void tearUp(){
        context.register(PropertyConfig.class);
        context.register(ServiceConfig.class);
        context.register(SecurityConfig.class);
        context.register(MapperConfig.class);
        context.refresh();
    }

    @Test
    public void testUser(){
        UserService userService = context.getBean(UserService.class);
        Long userId = 3L;
        GeneralResponseData data = userService.addUserRelation(userId);
        System.out.println(data.getMsg());
    }
}

2.采用spring-test

package com.wang.test;

import com.marsmother.commission.core.config.MapperConfig;
import com.marsmother.commission.core.config.PropertyConfig;
import com.marsmother.commission.core.config.ServiceConfig;
import com.marsmother.commission.core.dto.GeneralResponseData;
import com.marsmother.commission.core.service.UserService;
import com.marsmother.commission.site.config.SecurityConfig;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.test.context.ContextConfiguration;
import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;

/**
 * Created by Wanglei on 15/10/29.
 */
@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(classes = {PropertyConfig.class, ServiceConfig.class, SecurityConfig.class, MapperConfig.class})
public class SpringTest {

    @Autowired
    private UserService userService;

    @Test
    public void testUser(){
        GeneralResponseData data=  userService.addUserRelation(3L);
        System.out.println(data.getMsg());
    }

}

3.采用Mockito
需要引入相应包：

<dependency>
    <groupId>org.mockito</groupId>
    <artifactId>mockito-all</artifactId>
    <version>1.9.5</version>
    <scope>test</scope>
</dependency>

package com.wang.test;

import com.marsmother.commission.core.dto.GeneralResponseData;
import com.marsmother.commission.core.presistence.FollowNumberMapper;
import com.marsmother.commission.core.presistence.UserMapper;
import com.marsmother.commission.core.presistence.UserRelationMapper;
import com.marsmother.commission.core.service.UserService;
import org.junit.Before;
import org.junit.Test;
import org.mockito.InjectMocks;
import org.mockito.Mock;
import org.mockito.MockitoAnnotations;

/**
 * Created by Wanglei on 15/10/29.
 */
public class TestUserService {

    @InjectMocks
    private UserService userService;

    @Mock
    private FollowNumberMapper followNumberMapper;
    @Mock
    private UserMapper userMapper;
    @Mock
    private UserRelationMapper userRelationMapper;

    @Before
    public void init(){
        MockitoAnnotations.initMocks(this);
    }

    @Test
    public void testUser(){
        Long userId = 3L;
        GeneralResponseData result = userService.addUserRelation(userId);
        System.out.println(result.getMsg());
    }

}

这里@Mock的话，并不会真正的去执行数据库的操作。
还有一种用法是@Spy，暂时不了解具体使用方式，待研究。
相比之下，还是spring-test标准一些。
