1.首先创建Mavne项目。

第二步骤：

添加修改pom.xml

[html] view plain copy

<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">

</dependency>
<!-- JSTL（JSP Standard TagLibrary，JSP标准标签库)是一个不断完善的开放源代码的JSP标签库，是由apache的jakarta小组来维护的。JSTL只能运行在支持JSP1.2和Servlet2.3规范的容器上，如tomcat
4.x。在JSP2.0中也是作为标准支持的。不然报异常信息： javax.servlet.ServletException:Circular view
path [/helloJsp]: would dispatch back to the current handler URL[/helloJsp]
again. Check your ViewResolver setup! (Hint: This may be the resultof an
unspecified view, due to default view name generation.) -->

<configuration>

<target>1.8</target>

</plugins>
</build>
</project>

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
（

<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-thymeleaf</artifactId>
</dependency>
）

3.添加修改配置文件。

application.properties

[plain] view plain copy

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

[java] view plain copy

package web.spring_boot;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
@SpringBootApplication
public class TestA {
public static void main(String[] args) {
SpringApplication.run(TestA.class);
}
}

[java] view plain copy

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<String, Object> mytest() {
Map<String, Object> map = new HashMap<String, Object>();
map.put("name", "Ryan");
map.put("age", "3");
map.put("sex", "man");
return map;
}
}

index.jsp如下：

[html] view plain copy

<!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>xxxxxxxxxxxxxx
${sb}
</body>
</html>

然后启动就可以了
