SpringBoot+Maven项目实战（2）：集成SpringBoot

项目结构图

1.pom文件添加SpingBoot依赖

<?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.sbm</groupId>    <artifactId>SpringBoot_Maven</artifactId>    <version>1.0-SNAPSHOT</version>    <parent>        <groupId>org.springframework.boot</groupId>        <artifactId>spring-boot-starter-parent</artifactId>        <version>1.4.0.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>1.7</java.version>    </properties>    <dependencies>    <!--支持 Web 应用开发，包含 Tomcat 和 spring-mvc。 -->    <dependency>        <groupId>org.springframework.boot</groupId>        <artifactId>spring-boot-starter-web</artifactId>    </dependency>    <dependency>        <groupId>org.springframework.boot</groupId>        <artifactId>spring-boot-starter-test</artifactId>        <scope>test</scope>    </dependency>    <!--模板引擎-->    <!--  <dependency>          <groupId>org.springframework.boot</groupId>          <artifactId>spring-boot-starter-thymeleaf</artifactId>      </dependency>-->    <dependency>        <groupId>org.springframework.boot</groupId>        <artifactId>spring-boot-starter-freemarker</artifactId>    </dependency>    <!--Json Support-->    <dependency>        <groupId>com.alibaba</groupId>        <artifactId>fastjson</artifactId>        <version>1.1.43</version>    </dependency>    <!--springboot中修改完文件后自动reload的插件，修改完文件Ctrl + F9 Make一下就可以-->    <dependency>        <groupId>org.springframework</groupId>        <artifactId>springloaded</artifactId>        <version>1.2.3.RELEASE</version>    </dependency>    <!--springboot中修改完文件后自动reload的插件 end--></dependencies><build><plugins>    <plugin>        <groupId>org.springframework.boot</groupId>        <artifactId>spring-boot-maven-plugin</artifactId>        <dependencies>            <dependency>                <groupId>org.springframework</groupId>                <artifactId>springloaded</artifactId>                <version>1.2.3.RELEASE</version>            </dependency>        </dependencies>    </plugin></plugins></build>        <!--配置远程仓库地址--><repositories><repository>    <id>spring-milestone</id>    <url>https://repo.spring.io/libs-release</url></repository></repositories>        <!--配置远程仓库地址--><pluginRepositories><pluginRepository>    <id>spring-milestone</id>    <url>https://repo.spring.io/libs-release</url></pluginRepository></pluginRepositories></project>

2.编写启动类Applaction

package com.sbm;import org.apache.ibatis.session.SqlSessionFactory;import org.apache.tomcat.jdbc.pool.DataSource;import org.mybatis.spring.SqlSessionFactoryBean;import org.mybatis.spring.annotation.MapperScan;import org.mybatis.spring.mapper.MapperScannerConfigurer;import org.springframework.beans.factory.annotation.Autowired;import org.springframework.boot.SpringApplication;import org.springframework.boot.autoconfigure.EnableAutoConfiguration;import org.springframework.boot.autoconfigure.SpringBootApplication;import org.springframework.boot.context.properties.ConfigurationProperties;import org.springframework.context.annotation.Bean;import org.springframework.context.annotation.ComponentScan;import org.springframework.core.io.support.PathMatchingResourcePatternResolver;import org.springframework.jdbc.datasource.DataSourceTransactionManager;import org.springframework.transaction.PlatformTransactionManager;import org.springframework.transaction.annotation.EnableTransactionManagement;import org.springframework.web.bind.annotation.RequestMapping;import org.springframework.web.bind.annotation.RestController;/** * sbm * Created by yadong.zhang on com.sbm.application * User：yadong.zhang * Date：2016/10/20 * Time：18:15 *//** * 1).@SpringBootApplication标注启动配置入口，run()方法会创建一个Spring应用上下文(Application Context)。 * SpringBoot通过启动内嵌的Servlet容器（默认tomcat）用来处理Http请求。 * 2).@RestController是特殊的Controller，他的返回值直接作为Http Response的Body部分返回给浏览器 * 3).Spring WebMvc框架会将Servlet容器里收到的Http请求根据路径分发到对应的@Controller下进行处理。 */@EnableAutoConfiguration@SpringBootApplication@ComponentScan//@RestControllerpublic class Applaction {    @RequestMapping("/")    public String index(){        return "Spring Boot Application...";    }    public static void main(String[] args) {        SpringApplication.run(Applaction.class, args);    }}

3.编写控制类Controller

package com.sbm.controller;import com.sbm.service.IMessageService;import org.springframework.stereotype.Controller;import org.springframework.ui.Model;import org.springframework.web.bind.annotation.PathVariable;import org.springframework.web.bind.annotation.RequestMapping;import org.springframework.web.bind.annotation.ResponseBody;import javax.annotation.Resource;import java.util.Date;import java.util.HashMap;import java.util.Map;/** * sbm * Created by yadong.zhang on com.sbm.controller * User：yadong.zhang * Date：2016/10/20 * Time：18:26 */@Controllerpublic class HelloController {    @RequestMapping("/hello/{name}")    public String hello(@PathVariable("name") String name, Model model) {        model.addAttribute("name", name);        model.addAttribute("age","25");        model.addAttribute("sex","man");        model.addAttribute("birth",new Date());        return "hello";    }    @RequestMapping("/json")    @ResponseBody    public Map<String,Object> json(){        Map<String,Object> map = new HashMap<String,Object>();        map.put("name","Flyat");        map.put("age","25");        map.put("sex","man");        return map;    }}

4.测试页面访问看效果

 
 

前台页面渲染是使用的Freemarker模板，下节总结
