ROSE
2.1 基础环境
* 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
2.2 maven简介
* 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
2.3 项目建立
* 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
2.4 基础配置三步走
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-SNAPSHOT</version>
- </dependency>
- <dependency>
- <groupId>com.54chen</groupId>
- <artifactId>paoding-rose</artifactId>
- <version>1.0-SNAPSHOT</version>
- </dependency>
- <dependency>
- <groupId>com.54chen</groupId>
- <artifactId>paoding-rose-portal</artifactId>
- <version>1.0-SNAPSHOT</version>
- </dependency>
- <dependency>
- <groupId>com.54chen</groupId>
- <artifactId>paoding-rose-jade</artifactId>
- <version>1.1-SNAPSHOT</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>
- <?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>
2.5 hello world
* 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 cc0cc@126.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]。
