Spring boot 添加jsp模版支持

                                                                             Spring boot 添加jsp模版支持

1.0包结构如图：

2.0在pom.xml中加入如下配置：

<?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>com.yidigis</groupId>    <artifactId>wechat-system</artifactId>    <version>0.0.1-SNAPSHOT</version>    <packaging>jar</packaging>    <name>wechat-system</name>    <description>Demo project for Spring Boot</description>    <parent>        <groupId>org.springframework.boot</groupId>        <artifactId>spring-boot-starter-parent</artifactId>        <version>1.5.7.RELEASE</version>        <relativePath/> <!-- lookup parent from repository -->    </parent>    <properties>        <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>        <project.reporting.outputEncoding>UTF-8</project.reporting.outputEncoding>        <java.version>1.8</java.version>    </properties>    <dependencies>        <dependency>            <groupId>org.springframework.boot</groupId>            <artifactId>spring-boot-starter-web</artifactId>        </dependency>        <!--jpa的jar包 ，操作数据库的，类似hibernate -->        <dependency>            <groupId>org.springframework.boot</groupId>            <artifactId>spring-boot-starter-data-jpa</artifactId>        </dependency>        <!--mysql驱动 -->        <dependency>            <groupId>mysql</groupId>            <artifactId>mysql-connector-java</artifactId>        </dependency>        <!--配置servlet-->        <dependency>            <groupId>javax.servlet</groupId>            <artifactId>javax.servlet-api</artifactId>        </dependency>        <!--配置jsp jstl的支持-->        <dependency>            <groupId>javax.servlet</groupId>            <artifactId>jstl</artifactId>        </dependency>        <!--添加对tomcat的支持-->        <dependency>            <groupId>org.springframework.boot</groupId>            <artifactId>spring-boot-starter-tomcat</artifactId>            <scope>provided</scope>        </dependency>        <!--对jsp的支持-->        <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>            <plugin>                <groupId>org.springframework.boot</groupId>                <artifactId>spring-boot-maven-plugin</artifactId>                <configuration>                    <!--fork :  如果没有该项配置，肯呢个devtools不会起作用，即应用不会restart -->                    <fork>true</fork>                </configuration>            </plugin>        </plugins>    </build></project>

3.0编写application.properties配置文件；

server.port=80# 页面默认前缀目录 默认路径是  src/main/webappspring.mvc.view.prefix=/WEB-INF/jsp/# 响应页面默认后缀spring.mvc.view.suffix=.jsp# 自定义属性，可以在Controller中读取application.hello=Hello Angel From application###########################################################datasource -- 指定mysql数据库连接信息.########################################################spring.datasource.url = jdbc:mysql://localhost:3306/testspring.datasource.username = rootspring.datasource.password = rootspring.datasource.driverClassName = com.mysql.jdbc.Driverspring.datasource.max-active=20spring.datasource.max-idle=8spring.datasource.min-idle=8spring.datasource.initial-size=10

4.0编写controller控制器

package com.yidigis.controller;import org.springframework.beans.factory.annotation.Value;import org.springframework.stereotype.Controller;import org.springframework.web.bind.annotation.RequestMapping;import java.util.Map;@Controller@RequestMappingpublic class hellocontroller {        @Value("${application.hello:Hello Angel}")    private String hello;    @RequestMapping("/")    public String welcome(){        return "index";    }    @RequestMapping("/hello")    public String helloJsp(Map<String,Object> map){                System.out.println("HelloController.helloJsp().hello="+hello);        map.put("hello", hello);        return "/seller/hello";    }}

5.0 编写jsp页面：
