- 普通的pc机,del 380
- ubuntu 10.04基本不升级
- java version "1.6.0_29"
- eclipse
- m2clipse
- 茶一杯
- maven是基于项目对象模型(POM),可以通过一小段描述信息来管理项目的构建,报告和文档的软件项目管理工具。如果你已经有十次输入同样的Ant targets来编译你的代码、jar或者war、生成javadocs,你一定会自问,是否有一个重复性更少却能同样完成该工作的方法。Maven便提供了这样一种选择,将你的注意力从作业层转移到项目管理层。Maven项目已经能够知道如何构建和捆绑代码,运行测试,生成文档并宿主项目网页。
- maven对一个项目进入了固定的默认目录定义:
- src/main/java 写主要的java实现
- src/main/resources 写主要的配置文件
- src/test/java 写test case
- src/test/resources 写test case所需要的配置文件
- src/main/webapp [war项目特有]web项目的对外目录
- src/main/webapp/WEB-INF [war项目特有]web项目配置web.xml目录
- 打开eclipse(需要提前安装好m2clipse插件)
- new -> other -> maven -> maven project
- create a simple project
- next
- group id:com.54chen
- artifact id:rose-example
- packaging: war
- finished
###1)点火:基础的pom文件### 打开2.3建立好的项目,打开pom.xml,添加下面的段落到project中:
<dependencies>
<dependency>
<groupId>com.54chen</groupId>
<artifactId>paoding-rose-scanning</artifactId>
<version>1.0</version>
</dependency>
<dependency>
<groupId>com.54chen</groupId>
<artifactId>paoding-rose</artifactId>
<version>1.0</version>
</dependency>
<dependency>
<groupId>com.54chen</groupId>
<artifactId>paoding-rose-portal</artifactId>
<version>1.0</version>
</dependency>
<dependency>
<groupId>com.54chen</groupId>
<artifactId>paoding-rose-jade</artifactId>
<version>1.1</version>
</dependency>
</dependencies>
上述是rose环境最基础的依赖包。再添加一点常见的编译设置:
<build>
<resources>
<resource>
<directory>src/main/resources</directory>
<includes>
<include>**/*.*</include>
</includes>
</resource>
</resources>
<plugins>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-war-plugin</artifactId>
<version>2.0.2</version>
<configuration>
<webResources>
<resource>
<targetPath>WEB-INF</targetPath>
<filtering>true</filtering>
<directory>src/main/resources</directory>
<includes>
<include>**/*.xml</include>
<include>**/*.properties</include>
</includes>
<targetPath>WEB-INF</targetPath>
</resource>
</webResources>
</configuration>
</plugin>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-compiler-plugin</artifactId>
<configuration>
<source>1.6</source>
<target>1.6</target>
<fork>true</fork>
<verbose>true</verbose>
<encoding>UTF-8</encoding>
<compilerArguments>
<sourcepath>
${project.basedir}/src/main/java
</sourcepath>
</compilerArguments>
</configuration>
</plugin>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-surefire-plugin</artifactId>
<configuration>
<!-- 忽略测试 -->
<skip>true</skip>
</configuration>
</plugin>
</plugins>
</build>
上述是编译设置,也是放在project段落里。
###2)松离合:必不可少的web.xml### 在src/main/webapp/WEB-INF文件夹下建立web.xml:
<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns="http://java.sun.com/xml/ns/javaee" xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"
xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"
id="WebApp_ID" version="2.5">
<display-name>rose-example</display-name>
<welcome-file-list>
<welcome-file>index.html</welcome-file>
<welcome-file>index.htm</welcome-file>
<welcome-file>index.jsp</welcome-file>
<welcome-file>default.html</welcome-file>
<welcome-file>default.htm</welcome-file>
<welcome-file>default.jsp</welcome-file>
</welcome-file-list>
<context-param>
<param-name>log4jConfigLocation</param-name>
<param-value>/WEB-INF/log4j.xml</param-value>
</context-param>
<listener>
<listener-class>org.springframework.web.util.Log4jConfigListener</listener-class>
</listener>
<filter>
<filter-name>roseFilter</filter-name>
<filter-class>net.paoding.rose.RoseFilter</filter-class>
</filter>
<filter-mapping>
<filter-name>roseFilter</filter-name>
<url-pattern>/*</url-pattern>
<dispatcher>REQUEST</dispatcher>
<dispatcher>FORWARD</dispatcher>
<dispatcher>INCLUDE</dispatcher>
</filter-mapping>
</web-app>
###3)踩油门:applicationContext.xml### src/main/resources/applicationContext.xml是spring环境的油门,所有包的扫描和启动都在这里定义:
<?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"
xsi:schemaLocation="http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans-2.5.xsd
http://www.springframework.org/schema/context
http://www.springframework.org/schema/context/spring-context-2.5.xsd"
default-lazy-init="true">
<!-- 自动扫描 -->
<context:annotation-config />
<context:component-scan base-package="com.chen">
</context:component-scan>
</beans>
- 在src/main/java上右键 -> new -> package -> name: com.chen
- 在com.chen上右键 -> new -> package -> com.chen.controllers [controllers是rose框架默认的加载controller的package name]
- 在com.chen.controllers上右键 -> new -> class -> HelloController [*Controller是rose框架默认的controller层的class后缀]
- 打开HelloController这个类
- 在public class HelloController添加注解@Path("") [Path注解是rose框架提供的标识每个controller的对外访问时的基础路径]
- 在HelloController中添加方法
/**
* @author 54chen(陈臻) [chenzhen@xiaomi.com czhttp@gmail.com]
* @since 2012-4-10 上午11:14:46
*/
package com.chen.controllers;
import net.paoding.rose.web.annotation.Path;
import net.paoding.rose.web.annotation.rest.Get;
@Path("")
public class HelloController {
@Get("")
public String index() {
return "@hello world";
}
}
- [Get注解是rose框架提供的标识一个http访问是get还是post或者是其他,并且会将path与get中的字符串连接成一个url]
- 上述代码可以从浏览器访问:http://localhost/。
- 下述代码可以从浏览器访问:http://localhost/hello/world [注意path与get中的参数]。

package com.chen.controllers;
import net.paoding.rose.web.annotation.Path;
import net.paoding.rose.web.annotation.rest.Get;
@Path("/hello/")
public class HelloController {
@Get("world")
public String index() {
return "@hello world";
}
}
