spring-boot 添加JSP页面功能
转载
一、什么是Spring-Boot：
随着Spring 4新版本的发布，Spring Boot这个新的子项目得到了广泛的关注，因为不管是Spring 4官方发布的新闻稿还是针对首席架构师Adrian Colyer的专访，都对这个子项目所带来的生产率提升赞誉有加。
Spring Boot充分利用了JavaConfig的配置模式以及“约定优于配置”的理念，能够极大的简化基于Spring MVC的Web应用和REST服务开发。
Spring 4倡导微服务的架构，针对这一理念，近来在微博上也有一些有价值的讨论，如这里和这里。微服务架构倡导将功能拆分到离散的服务中，独立地进行部署，Spring Boot能够很方便地将应用打包成独立可运行的JAR包，因此在开发模式上很契合这一理念。目前，Spring Boot依然是0.5.0的里程碑版本，因此相关的文档尚不完善，本文将会以一个简单的样例来介绍基于这个项目的开发过程。
二、添加Spring-Boot 支持jsp 和rest的POM

三、新建Maven项目--webapp（略过）
四、添加配置Main类
package com.activity;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.EnableAutoConfiguration;
import org.springframework.boot.builder.SpringApplicationBuilder;
import org.springframework.boot.context.web.SpringBootServletInitializer;
import org.springframework.context.annotation.ComponentScan;
import org.springframework.context.annotation.Configuration;
@Configuration
@EnableAutoConfiguration //本人表示，一定要有这个标签(不然，你会吃亏的)
@ComponentScan
public class SampleWebJspApplication extends SpringBootServletInitializer {
@Override
protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
return application.sources(SampleWebJspApplication.class);
}
public static void main(String[] args) throws Exception {
SpringApplication.run(SampleWebJspApplication.class, args);
}
} |
五，加入application.properties到src/main/resources (这里映射了jsp路径和定义一些消息)
spring.view.prefix: /WEB-INF/jsp/ spring.view.suffix: .jsp application.message: Hello Phil |
这样基本就可以了。接下来测试RestControl和Control
@Resetcontrol 用于返回对象，会自动格式化为JSON
@Control会返回jsp页面
六，定义返回JSON数据
package com.activity.action;
import java.util.Date;
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 com.activity.model.bean;
import com.activity.model.tasker;
@RestController
public class demo {
@RequestMapping(value="/greeting")
public tasker test(@RequestParam String id) {
tasker e = new tasker();
e.setTaskerId(id);
e.setBegin_time(new Date());
e.setEnd_time(new Date());
e.setTargetUrl("baidu.com");
e.setType("123123");
e.setOperation("1,2,3,4,5,6");
return e;
}
@RequestMapping(value="/account")
public bean test_two() {
bean b = new bean();
b.setId("111");
b.setMobiPhone("shaoyongyang");
b.setPassWord("helloworld");
b.setUserName("bianbian");
return b;
}
@RequestMapping(value="/admin",method=RequestMethod.GET)
public String doView () {
return "index.jsp";
}
} |
七，返回jsp对象
package com.activity.action;
import java.util.Date;
import java.util.Map;
import javax.servlet.http.HttpServletRequest;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.servlet.ModelAndView;
import com.activity.service.infoService;
@Controller
public class InfoController {
private HttpServletRequest request ;
private infoService infoService ;
public infoService getInfoService() {
return infoService;
}
public void setInfoService(infoService infoService) {
this.infoService = infoService;
}
/***
* @author
* @since
@Value("${application.message:Hello World}")
private String message = "Hello World";
@RequestMapping("/index")
public String index(Map<String, Object> model) {
model.put("time", new Date());
model.put("message", this.message);
return "index";
/***当返回index字符串，会自动去WEB-INF JSP路径寻找index.jsp*/
}
/***
* @author
* @since
@RequestMapping(value="example")
public ModelAndView example(HttpServletRequest request) {
return new ModelAndView("index.jsp");
}
} |
至此。OVER！！！
