springboot搭建

1.首先创建Mavne项目。

第二步骤：

添加修改pom.xml

 <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">

以上特意注意2点 。如果想要添加jsp，(org.apache.tomcat.embed 是支持jsp格式，Javax.serlet.jsp.jstl是支持jsp一些语法）标准的2个。否则加载不了jsp文件。
如果不想用jsp，使用模板的话，具体jsp和模板的区别，可以单独百度。使用模板可以用一下内容
（


org.springframework.boot
spring-boot-starter-thymeleaf

）

3.添加修改配置文件。

application.properties

 spring.datasource.driver-class-name=com.mysql.jdbc.Driver
 spring.datasource.url=jdbc:mysql://localhost:3306/test?useUnicode=true&autoReconnect=true&characterEncoding=UTF-8&rewriteBatchedStatements=TRUE
 spring.datasource.username=root
 spring.datasource.password=****
 spring.datasource.max-active=10
 spring.datasource.max-idle=5
 spring.datasource.min-idle=0


 server.port=8082
 server.session.timeout=10
 server.tomcat.max-threads=800
 server.tomcat.uri-encoding=UTF-8
 # MVC  分版本
 spring.mvc.view.prefix=/WEB-INF/views/
 spring.mvc.view.suffix=.jsp

这里配置的是jsp的位置以及数据库一些配置。
添加文件。

4.添加程序

 package web.spring_boot;


 import org.springframework.boot.SpringApplication;
 import org.springframework.boot.autoconfigure.SpringBootApplication;


 @Configuration @EnableAutoConfiguration @ComponentScan("cn.yinchong.controller")
 public class TestA {
     public static void main(String[] args) {
         SpringApplication.run(TestA.class);
     }
 }

 package web.spring_boot.controller;


 import java.util.HashMap;
 import java.util.Map;


 import org.springframework.boot.builder.SpringApplicationBuilder;
 import org.springframework.boot.web.support.SpringBootServletInitializer;
 import org.springframework.stereotype.Controller;
 import org.springframework.ui.Model;
 import org.springframework.web.bind.annotation.RequestMapping;
 import org.springframework.web.bind.annotation.ResponseBody;


 @Controller
 public class SampleController extends SpringBootServletInitializer {


     @Override
     protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
         return application.sources(SampleController.class);
     }


     @RequestMapping("/")
     @ResponseBody
     String home() {
         System.out.println("xxxxxxxxxxxxx");
         return "Hello 22!";
     }


     //这里指定是条状的jsp界面
     @RequestMapping(value = "/index")
     public String index(Model model) {
         model.addAttribute("sb", "this is my fries测试不是好领导了副经理看fjldj 1123123");
         return "index";
     }


     @RequestMapping(value = "json")
     @ResponseBody
     public Map mytest() {
         Map map = new HashMap();
         map.put("name", "Ryan");
         map.put("age", "3");
         map.put("sex", "man");
         return map;
     }
 }

index.jsp如下：

 >
 <html>
 <head>
 <meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1">
 <title>Insert title heretitle>
 head>
 <body>xxxxxxxxxxxxxx
 ${sb}
 body>
 html>
