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：

org.mockito

mockito-all

1.9.5

test

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。
