Spring框架整合第二弹； SpringMVC单独使用maven-jetty-plugin运行服务
基本问题
-
如何搭建一个可用的本地测试server？
-
怎么使用SpringMVC开发一个API？
事前准备
-
maven webapp项目创建
-
完成后的文件布局
pom.xml中的配置
- 添加property节点，统一管理spring那么多包的版本
<properties>
<spring.version>4.0.2.RELEASE</spring.version>
</properties>
- 添加Spring相关依赖
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-core</artifactId>
<version>${spring.version}</version>
</dependency>
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-web</artifactId>
<version>${spring.version}</version>
</dependency>
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-webmvc</artifactId>
<version>${spring.version}</version>
</dependency>
- 添加maven-jetty-plugin插件
<plugins>
<plugin>
<groupId>org.eclipse.jetty</groupId>
<artifactId>jetty-maven-plugin</artifactId>
<version>9.2.13.v20150730</version>
</plugin>
</plugins>
配置web.xml文件
- 这个文件是webapp的配置文件
<!DOCTYPE web-app PUBLIC
"-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN"
"http://java.sun.com/dtd/web-app_2_3.dtd" >
<web-app>
<display-name>Archetype Created Web Application</display-name>
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>/WEB-INF/mvc-dispatcher-servlet.xml</param-value>
</context-param>
<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>
<servlet>
<servlet-name>mvc-dispatcher</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>mvc-dispatcher</servlet-name>
<url-pattern>/</url-pattern>
</servlet-mapping>
</web-app>
配置mvc-dispatcher-servlet.xml文件
- springmvc的配置文件
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:context="http://www.springframework.org/schema/context"
xmlns:mvc="http://www.springframework.org/schema/mvc"
xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc.xsd">
<context:component-scan base-package="com.zzj.controller"/>
<mvc:annotation-driven/>
</beans>
新建Controller
- 需要用注解来驱动
package com.zzj.controller;
import org.springframework.http.HttpStatus;
import org.springframework.http.ResponseEntity;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
/**
* Created by zhangzj on 2016/10/13.
*/
@Controller
@RequestMapping("/user")
public class UserController {
@RequestMapping(value = "/", method = RequestMethod.GET)
public ResponseEntity getUser(){
return new ResponseEntity("user body", HttpStatus.OK);
}
}
运行服务
- 在项目目录下运行命令
mvn jetty:run
小结
-
SpringMVC作用貌似是根据请求路径反应的这个一个东西，注解驱动很有趣
-
maven-jetty-plugin内置的webserver，部署测试很方便
