开发支持JSP的web应用 - morris131/morris-book GitHub Wiki

  1. 新建spring boot项目，编写pom.xml

详细代码参考pom.xml

<?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">

        </dependency>

        <!-- servlet依赖. -->

        <dependency>

            <groupId>javax.servlet</groupId>

            <artifactId>javax.servlet-api</artifactId>

            <scope>provided</scope>

        <!-- tomcat的支持.-->

        <dependency>

            <groupId>org.springframework.boot</groupId>

            <artifactId>spring-boot-starter-tomcat</artifactId>


        </dependency>

        <dependency>

            <groupId>org.apache.tomcat.embed</groupId>
            <artifactId>tomcat-embed-jasper</artifactId>
        </dependency>

    </dependencies>

    <build>
        <plugins>
            <plugin>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-maven-plugin</artifactId>
            </plugin>
        </plugins>

    </build>


</project>

tomcat-embed-jasper和spring-boot-starter-tomcat依赖不要带provided属性

  1. 编写HelloController

详细代码参考HelloController.java

package com.morris.web;

import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.RequestMapping;

/**
 * Created by lian.chen on 2017/6/15.
 */
@Controller
public class HelloController {

    @RequestMapping("/hello")
    public String hello(Model model) {
        model.addAttribute("msg","hello world");
        return "hello";
    }


}
  1. 编写jsp页面

详细代码参考hello.jsp

<!DOCTYPE html>
<html lang="en">
<body>
<h1>Message: ${msg}</h1>
</body>
</html>
  1. 在配置文件application.properties中添加

详细代码参考application.properties

spring.mvc.view.prefix=/WEB-INF/jsp/
spring.mvc.view.suffix=.jsp
  1. 启动项目

在浏览器输入 http://localhost:8080/hello
