SpringMVC单元测试之MockMVC，模拟登入用户

今天介绍一下springMVC的单元测试，可以参考spring官方文档进行

前提准备，springmvc的demo工程，这里就不做叙述了

controller层

package controller;

import javax.servlet.http.HttpSession;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.RequestParam;
import org.springframework.web.bind.annotation.RestController;

import service.UserService;
import domain.User;

/**
 * UserController.
 * @author Leon Lee
 */
@RestController
@RequestMapping(value = "user")
public class UserController {

	/**
	 * UserService interface.
	 */
	@Autowired
	private UserService userService;

	/**
	 * Get user MSG.
	 * @param userId
	 * @return user Msg
	 */
	@RequestMapping(value = "userMsg/{userId}", method = RequestMethod.GET)
	public User getUserMsg(@PathVariable(value = "userId") String userId) {
		return userService.getUserMsg(userId);
	}
	
	/**
	 * Update user MSG.
	 * @param userId
	 * @param userName
	 * @return updated user MSG
	 */
	@RequestMapping(value = "userMsg/{userId}", method = RequestMethod.PUT)
	public User putUserMsg(@PathVariable(value = "userId") String userId, @RequestParam String userName,HttpSession session){
		if(null == (String)session.getAttribute("loginUser"))
			return new User();
		System.out.println((String)session.getAttribute("loginUser"));
		return userService.putUserMsg(userId, userName);
	}
	
	/**
	 * Delete user.
	 * @param userId
	 * @return deleted user MSG
	 */
	@RequestMapping(value = "userMsg/{userId}", method = RequestMethod.DELETE)
	public User delUserMsg(@PathVariable(value = "userId") String userId){
		return userService.delUserMsg(userId);
	}
	
	/**
	 * Add user.
	 * @param userName
	 * @return added user MSG
	 */
	@RequestMapping(value = "userMsg", method = RequestMethod.POST)
	public User postUserMsg(@RequestParam String userName){
		return userService.postUserMsg(userName);
	}
	
	/**
	 * login User. Note that do not send password as url.
	 * @param userId
	 * @param password
	 * @return
	 */
	@RequestMapping(value = "userMsg/{userId}/{password}", method = RequestMethod.GET)
	public boolean loginUser(@PathVariable String userId, @PathVariable String password, HttpSession session){
		if("loginUser".equals(userId)&&"loginUser".equals(password)){
			session.setAttribute("loginUser", userId);
			return true;
		}
		return false;
	}
}

单元测试类

这里的静态导入比较重要，有时候没办法自动导入的

就是下面的 import static xxx.*

另一点，

@ContextConfiguration(locations = {"classpath:applicationContext.xml","classpath:applicationContext.mvc.xml"})

代表的是加载的配置文件，可以根据需要进行添加

package controller.test;

import static org.springframework.test.web.servlet.result.MockMvcResultHandlers.*;
