搭建一个简单的安卓应用的服务端。采用Struts2+hibernate的架构。IDE使用eclipse，数据库使用MySQL。搭建java开发环境就不说了，百度一大把。

一、项目结构

本人主要是android开发，了解一点java服务器开发，借用这个机会熟悉一下服务端开发。个人感觉使用Struts就是配置麻烦，先把整个项目的结构图PO在下面，配置随后附上。

项目结构如下图所示：

二、项目介绍

1、数据库hibernate配置：hibernate.cfg.xml

<?xml version="1.0" encoding="utf-8"?>
    <!DOCTYPE hibernate-configuration PUBLIC
    "-//Hibernate/Hibernate Configuration DTD 3.0//EN"
    "http://www.hibernate.org/dtd/hibernate-configuration-3.0.dtd">
    <hibernate-configuration>
        <session-factory>
            <property name="hibernate.bytecode.use_reflection_optimizer">false</property>
            <property name="hibernate.c3p0.acquire_increment">2</property>
            <property name="hibernate.c3p0.idle_test_period">120</property>
            <property name="hibernate.c3p0.max_size">50</property>
            <property name="hibernate.c3p0.max_statements">0</property>
            <property name="hibernate.c3p0.min_size">2</property>
            <property name="hibernate.c3p0.timeout">120</property>
            <property name="hibernate.c3p0.validate">true</property>
            <property name="hibernate.connection.driver_class">com.mysql.jdbc.Driver</property>
            <property name="hibernate.connection.url">jdbc:mysql://127.0.0.1/keng</property>
            <property name="hibernate.connection.username">admin</property>
            <property name="hibernate.connection.password">admin</property>
            <property name="hibernate.dialect">org.hibernate.dialect.MySQLDialect</property>
            <property name="hibernate.search.autoregister_listeners">false</property>
            <property name="hibernate.show_sql">true</property>
            <property name="hibernate.validator.apply_to_ddl">false</property>
            <mapping class="com.hy.keng.data.User" />
        </session-factory>
    </hibernate-configuration>

2、Struts配置：struts.xml

<?xml version="1.0" encoding="UTF-8"?>
    <!DOCTYPE struts PUBLIC
        "-//Apache Software Foundation//DTD Struts Configuration 2.3//EN"
        "http://struts.apache.org/dtds/struts-2.3.dtd">
    <struts>
    	<constant name="struts.devMode" value="true" />
    	<constant name="struts.action.extension" value="ss" />
    	<constant name="struts.i18n.encoding" value="UTF-8" />
    	<constant name="struts.allowed.action.names" value="[a-zA-Z0-9_]{3,50}" />
    	<constant name="struts.multipart.saveDir" value="/tmp"></constant>
    	<constant name="struts.enable.DynamicMethodInvocation" value="false" />
    	<constant name="struts.multipart.maxSize" value="100000000" />
    	<constant name="struts.ognl.allowStaticMethodAccess" value="true" />
    
    	<package name="v1_user_json" extends="json-default" namespace="/client">
    		<action name="*_*_j" class="com.hy.keng.action.{1}" method="{2}">
    			<result name="json" type="json">
    				<param name="ignoreHierarchy">false</param>
    				<param name="excludeProperties">texts,actionErrors,actionMessages,errorMessages,errors,fieldErrors,locale</param>
    				<param name="noCache">true</param>
    				<param name="excludeNullProperties">true</param>
    				<param name="contentType">text/plain</param>
    			</result>
    			
    			<result name="error">errorjson.jsp</result>
    		</action>
    		<action name="*_j" class="com.hy.keng.action.{1}">
    			<result name="json" type="json">
    				<param name="ignoreHierarchy">false</param>
    				<param name="excludeProperties">texts,actionErrors,actionMessages,errorMessages,errors,fieldErrors,locale</param>
    				<param name="noCache">true</param>
    				<param name="excludeNullProperties">true</param>
    				<param name="contentType">text/plain</param>
    			</result>
    			<result name="error">errorjson.jsp</result>
    		</action>
    	</package>
    </struts>

3、web配置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"
    	xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd"
    	id="WebApp_ID" metadata-complete="true" version="3.0">
    	<display-name>keng</display-name>
    	<filter>
    		<filter-name>ExpiresFilter</filter-name>
    		<filter-class>org.apache.catalina.filters.ExpiresFilter</filter-class>
    		<init-param>
    			<param-name>ExpiresByType text/html</param-name>
    			<param-value>access plus 0 seconds</param-value>
    		</init-param>
    	</filter>
    	<filter-mapping>
    		<filter-name>ExpiresFilter</filter-name>
    		<url-pattern>*.ss</url-pattern>
    	</filter-mapping>
    	<filter>
    		<filter-name>struts2</filter-name>
    		<filter-class>org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter</filter-class>
    	</filter>
    	<filter-mapping>
    		<filter-name>struts2</filter-name>
    		<url-pattern>*.ss</url-pattern>
    	</filter-mapping>
    </web-app>

三、数据库介绍

数据库使用的是MySQL，数据库管理工具用的是heidisql。

mysql的安装和配置过程我就不说了，打开heidisql，输入本机ip和账号密码

![Center 1][]

进入后新建数据库keng，然后再新建一张数据表user，建表语句如下：

CREATE TABLE `user` (
    	`id` INT(11) NOT NULL AUTO_INCREMENT COMMENT 'ID',
    	`username` VARCHAR(50) NOT NULL COMMENT '用户名' COLLATE 'utf8mb4_unicode_ci',
    	`nickname` VARCHAR(50) NULL DEFAULT NULL COMMENT '昵称' COLLATE 'utf8mb4_unicode_ci',
    	PRIMARY KEY (`id`),
    	INDEX `username` (`username`)
    )
    COMMENT='用户表'
    COLLATE='utf8mb4_unicode_ci'
    ENGINE=InnoDB
    AUTO_INCREMENT=2;

然后添加两条数据进去就可以测试了。

四、测试

打开浏览器，输入地址，正确结果如下：

![Center 3][]

用户不存在结果如下：
