Spring MVC基础-测试

【博文目录>>>】

【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;

/**

* All Rights Reserved !!!
*/
@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;

/**

* Date: 2017-07-14 20:42

*/
@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";
}
}


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 !!!
*/
@RestController
public 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.web.servlet.config.annotation.WebMvcConfigurerAdapter;
import org.springframework.web.servlet.view.InternalResourceViewResolver;
import org.springframework.web.servlet.view.JstlView;

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");
}
}
