spring boot + jsp

创建一个spring　boot + jsp的工程

 

1.   首先创建一个maven工程boot-Spring-web:

整体目录结构:

2.   在pom文件导入以下依赖, 然后会自动导入相应的包:

<?xml version="1.0" encoding="UTF-8"?><project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"         xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">  <modelVersion>4.0.0</modelVersion><groupId>cn.boot.com</groupId>  <artifactId>bootForSpring</artifactId>  <version>0.0.1-SNAPSHOT</version><packaging>war</packaging><name>spring-web-demo</name><description>Demo project for Spring WebMvc</description><parent><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-parent</artifactId><version>1.2.5.RELEASE</version><relativePath /></parent><properties><project.build.sourceEncoding>UTF-8</project.build.sourceEncoding><java.version>1.8</java.version></properties><dependencies><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-web</artifactId></dependency><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-tomcat</artifactId><scope>provided</scope></dependency><dependency><groupId>org.apache.tomcat.embed</groupId><artifactId>tomcat-embed-jasper</artifactId><scope>provided</scope></dependency><dependency><groupId>javax.servlet</groupId><artifactId>jstl</artifactId></dependency><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-test</artifactId><scope>test</scope></dependency></dependencies><build><plugins><plugin><groupId>org.springframework.boot</groupId><artifactId>spring-boot-maven-plugin</artifactId></plugin></plugins></build></project>

3.   创建User.java实体类:

package cn.boot.com.bootForSpring.domain;public class User {      private Long id;      private String name;        public Long getId() {          return id;      }        public void setId(Long id) {          this.id = id;      }        public String getName() {          return name;      }        public void setName(String name) {          this.name = name;      }        @Override      public boolean equals(Object o) {          if (this == o) return true;          if (o == null || getClass() != o.getClass()) return false;            User user = (User) o;            if (id != null ? !id.equals(user.id) : user.id != null) return false;            return true;      }        @Override      public int hashCode() {          return id != null ? id.hashCode() : 0;      }@Overridepublic String toString() {return "User [id=" + id + ", name=" + name + "]";}  } 

创建controller:

TaskController.java: @Controller标签:返回jsp视图.

package cn.boot.com.bootForSpring.controller;import java.util.Map;import org.springframework.stereotype.Controller;import org.springframework.ui.Model;import org.springframework.web.bind.annotation.ModelAttribute;import org.springframework.web.bind.annotation.RequestMapping;import cn.boot.com.bootForSpring.domain.User;/** * 返回jsp的视图 * @author Administrator * */@Controller@RequestMapping("/task")public class TaskController {/** * 用model传参 * @param model * @return */  @RequestMapping("/hello")    public String greeting(Model model, @ModelAttribute("user") User user) {  model.addAttribute("hahaha", "成功了");  System.out.println(user);        return "helloWord";    }    /**   * 用map传参   * @param model   * @return   */  @RequestMapping("/helloWord")  public String helloWord(Map<String, Object> model) {  model.put("hahaha", "成功了");  return "helloWord";  }}

和UserController.java: @RestController标签:返回json.

package cn.boot.com.bootForSpring.web;import javax.servlet.http.HttpServletRequest;import org.springframework.boot.SpringApplication;import org.springframework.boot.autoconfigure.EnableAutoConfiguration;import org.springframework.web.bind.annotation.ModelAttribute;import org.springframework.web.bind.annotation.PathVariable;import org.springframework.web.bind.annotation.RequestMapping;import org.springframework.web.bind.annotation.RestController;import cn.boot.com.bootForSpring.domain.User;//@SpringBootApplication标签或@EnableAutoConfiguration都行(开启自动配置)//@SpringBootApplication@EnableAutoConfiguration@RestController @RequestMapping("/user")  public class UserController {        @RequestMapping("/{id}")      public User view(@PathVariable("id") Long id, @ModelAttribute("user") User user1) {     System.out.println(user1);        User user = new User();          user.setId(id);          user.setName("zhang");          return user;      }      @RequestMapping("/hello/{id}")      public User hello(@PathVariable("id") Long id,User user, HttpServletRequest request) {     System.out.println(user);    System.out.println(request.getParameter("name"));    return user;      }          @RequestMapping("/stringValue")      public User hello(String str, HttpServletRequest request) {     System.out.println(str);    User user = new User();    return user;      }        public static void main(String[] args) {          SpringApplication.run(UserController.class);      }    }  

Jsp文件:

<%@ page language="java" contentType="text/html; charset=utf-8"    pageEncoding="utf-8"%><!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"><html><head><meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1"><title>Insert title here</title></head><body>成功了<b />哈哈哈<b />${hahaha}<input type="submit" value="提交" id="tijiao"/></body><script src="/js/jquery-1.7.2.min.js"></script><script>$(function(){$('#tijiao').click(function(){alert("传数据");var param = {id : 1, name : '哈哈'};var url = "http://localhost:8080/task/hello";$.ajax({ type:"get", url:url, data: param, dataType:'html', cache : false, async: false, success:function(data){ if(data.code == "000000"){ layer.alert('操作成功'); }else{ layer.alert('操作失败'); } }})});});</script></html>

Js位置:

application.properties文件:

spring.view.prefix: /WEB-INF/jsp/spring.view.suffix: .jspapplication.message: Hello Phil

SampleWebJspApplication.java:启动服务器(main()方法启动):

package cn.boot.com.bootForSpring;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@ComponentScanpublic class SampleWebJspApplication extends SpringBootServletInitializer {@Overrideprotected SpringApplicationBuilder configure(SpringApplicationBuilder application) {return application.sources(SampleWebJspApplication.class);}public static void main(String[] args) throws Exception {SpringApplication.run(SampleWebJspApplication.class, args);}}
