今天介紹一下springMVC的單元測試，可以參考spring官方文件進行

前提準備，springmvc的demo工程，這裡就不做敘述了

controller層

package controller;

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;

 */
@RestController

	 */

	}
	
	/**

	 * @param userId
	 * @return deleted user MSG
	 */

	}
	
	/**
	 * login User. Note that do not send password as url.
	 * @param userId
	 * @param password
	 * @return
	 */

	public boolean loginUser(@PathVariable String userId, @PathVariable String password, HttpSession session){
		if("loginUser".equals(userId)&&"loginUser".equals(password)){

			return true;
		}
		return false;
	}
}
 

單元測試類

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

代表的是載入的配置檔案，可以根據需要進行新增
