测试是保证软件质量的关键,为了测试Web 项目通常不需要启动项目,我们需要一些Servlet 相关的模拟对象,比如:MockMVC 、MockHttpServletRequest 、MockHttpServletResponse 、MockHttpSession 等。在Spring 里,我们使用@WebAppConfiguration 指定加载的ApplicationContext 是一个WebApplicationContext 。通过他来模拟一个web测试环境。Spring提供了非常丰富的测试功能。本例就演示如何使用Spring测试。

【代码实现】

package com.example.spring.framework.test.service;

import org.springframework.stereotype.Service;

/**

@Service
public class DemoService {
    public String saySomething() {
        return  "hello";
    }
}
package com.example.spring.framework.test.controller;

import com.example.spring.framework.test.service.DemoService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.RequestMapping;

@Controller
public class NormalController {
    @Autowired
    DemoService demoService;

    @RequestMapping(value = "/normal", produces = "text/plain;charset=UTF-8")
    public String testPage(Model model) {
        model.addAttribute("msg", demoService.saySomething());

        return "page";
    }
}

    @Autowired

    @RequestMapping(value = "/testRest", produces = "text/plain;charset=UTF-8")
    public @ResponseBody String testRest() {
        return demoService.saySomething();
    }
