Spring MVC基础-测试

【测试】

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;/** * Author: 王俊超 * Date: 2017-07-14 08:14 * All Rights Reserved !!! */@Servicepublic 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;/** * Author: 王俊超 * Date: 2017-07-14 20:42 * All Rights Reserved !!! */@Controllerpublic 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";    }}

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.web.bind.annotation.RequestMapping;import org.springframework.web.bind.annotation.ResponseBody;import org.springframework.web.bind.annotation.RestController;/** * Author: 王俊超 * Date: 2017-07-14 20:45 * All Rights Reserved !!! */@RestControllerpublic class MyRestController {    @Autowired    DemoService demoService;    @RequestMapping(value = "/testRest", produces = "text/plain;charset=UTF-8")    public @ResponseBody String testRest() {        return demoService.saySomething();    }}

package com.example.spring.framework.test.config;import org.springframework.context.annotation.Bean;import org.springframework.context.annotation.ComponentScan;import org.springframework.context.annotation.Configuration;import org.springframework.scheduling.annotation.EnableScheduling;import org.springframework.web.servlet.config.annotation.EnableWebMvc;import org.springframework.web.servlet.config.annotation.ResourceHandlerRegistry;import org.springframework.web.servlet.config.annotation.ViewControllerRegistry;import org.springframework.web.servlet.config.annotation.WebMvcConfigurerAdapter;import org.springframework.web.servlet.view.InternalResourceViewResolver;import org.springframework.web.servlet.view.JstlView;/** * Author: 王俊超 * Date: 2017-07-14 08:15 * All Rights Reserved !!! */@Configuration@EnableWebMvc@EnableScheduling@ComponentScan("com.example.spring.framework.test")public class MyMvcConfig extends WebMvcConfigurerAdapter {    @Bean    public InternalResourceViewResolver viewResolver() {        InternalResourceViewResolver viewResolver = new InternalResourceViewResolver();        viewResolver.setPrefix("/WEB-INF/classes/views/");        viewResolver.setSuffix(".jsp");        viewResolver.setViewClass(JstlView.class);        return viewResolver;    }    @Override    public void addResourceHandlers(ResourceHandlerRegistry registry) {        registry.addResourceHandler("/assets/**").addResourceLocations("classpath:/assets/");        super.addResourceHandlers(registry);    }    @Override    public void addViewControllers(ViewControllerRegistry registry) {        registry.addViewController("/see").setViewName("/see");        registry.addViewController("/async").setViewName("/async");    }}
