springmore-让编程更容易

这是我多年项目的总结，并将其抽象出来，形成一个开源的项目

部分借鉴springside,将更多的实践总结进来

基于spring+ibatis+springMVC

springmore-core专注于一些核心的应用，目前是读写分离组件

springmore-commons实用工具类

如：StringUtil,FileUtil,DateUtil,HTTPClientUtil,FTPUtil,DesUtil,ExcelUtil,XMLUtil等等

springmore-redis 封装Jedis

springmore-core

spring+ibatis实现读写分离

特点

无缝结合spring+ibatis，对于程序员来说，是透明的

除了修改配置信息之外，程序的代码不需要修改任何东西

支持spring的容器事务
规则:

基于spring配置的容器事务
读写事务到主库
只读事务到从库
如果没有配置事务，更新语句全部到主库，查询语句均衡到从库

dataSource配置(applicationContext.xml中)

<?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-3.0.xsd   http://www.springframework.org/schema/context   http://www.springframework.org/schema/context/spring-context-3.0.xsd   ">  <!-- C3P0连接池配置 -->  <bean id="master" class="com.mchange.v2.c3p0.ComboPooledDataSource">   <property name="driverClass">    <value>com.mysql.jdbc.Driver</value>   </property>   <property name="jdbcUrl">    <value>jdbc:mysql://192.168.1.246:3306/db1</value>   </property>   <property name="user">    <value>ysb</value>   </property>   <property name="password">    <value>ysb</value>   </property>   <property name="initialPoolSize">    <value>20</value>   </property>   <property name="minPoolSize">    <value>20</value>   </property>   <property name="maxPoolSize">    <value>200</value>   </property>   <property name="maxIdleTime">    <value>255000</value>   </property>  </bean>  <bean id="dataSource2" class="com.mchange.v2.c3p0.ComboPooledDataSource">  <property name="driverClass">   <value>com.mysql.jdbc.Driver</value>  </property>  <property name="jdbcUrl">   <value>jdbc:mysql://192.168.1.246:3306/db2</value>  </property>  <property name="user">   <value>ysb</value>  </property>  <property name="password">   <value>ysb</value>  </property>  <property name="initialPoolSize">   <value>20</value>  </property>  <property name="minPoolSize">   <value>20</value>  </property>  <property name="maxPoolSize">   <value>200</value>  </property>  <property name="maxIdleTime">   <value>255000</value>  </property> </bean>  <bean id="dataSource3" class="com.mchange.v2.c3p0.ComboPooledDataSource">  <property name="driverClass">   <value>com.mysql.jdbc.Driver</value>  </property>  <property name="jdbcUrl">   <value>jdbc:mysql://192.168.1.246:3306/db3</value>  </property>  <property name="user">   <value>ysb</value>  </property>  <property name="password">   <value>ysb</value>  </property>  <property name="initialPoolSize">   <value>20</value>  </property>  <property name="minPoolSize">   <value>20</value>  </property>  <property name="maxPoolSize">   <value>200</value>  </property>  <property name="maxIdleTime">   <value>255000</value>  </property> </bean>  <bean id="dataSource" class="org.springmore.core.datasource.DynamicDataSource">  <property name="master" ref="master" />    <property name="slaves">   <list>    <ref bean="dataSource2"/>    <ref bean="dataSource3"/>   </list>     </property> </bean> </beans>

整合mybatis配置(applicationContext.xml中)

 <!-- ibatis3 工厂类 -->  <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">   <property name="dataSource" ref="dataSource" />   <property name="configLocation" value="classpath:sqlMapConfig.xml" />  </bean>  <bean id="sqlSessionTemplate" class="org.mybatis.spring.SqlSessionTemplate">   <constructor-arg index="0" ref="sqlSessionFactory" />  </bean>    <bean id="dynamicSqlSessionTemplate" class="org.springmore.core.datasource.DynamicSqlSessionTemplate">   <constructor-arg index="0" ref="sqlSessionTemplate" />  </bean>

事务配置(applicationContext.xml中)

 <!-- 定义单个jdbc数据源的事务管理器 -->  <bean id="transactionManager"   class="org.springmore.core.datasource.DynamicDataSourceTransactionManager">   <property name="dataSource" ref="dataSource" />  </bean>  <!-- 以 @Transactional 标注来定义事务  -->  <tx:annotation-driven transaction-manager="transactionManager"   proxy-target-class="true" />      <!-- 配置事务的传播特性 -->  <tx:advice id="txAdvice" transaction-manager="transactionManager">   <tx:attributes>    <tx:method name="insert*" propagation="REQUIRED" read-only="false"     rollback-for="Exception" />    <tx:method name="delete*" propagation="REQUIRED" read-only="false"     rollback-for="Exception" />    <tx:method name="update*" propagation="REQUIRED" read-only="false"     rollback-for="Exception" />    <tx:method name="proc*" propagation="REQUIRED" read-only="false"     rollback-for="Exception" />    <tx:method name="select*" read-only="true" />    <tx:method name="*" read-only="false" />    <!-- <tx:method name="*" read-only="true" /> -->   </tx:attributes>  </tx:advice>  <!-- 那些类的哪些方法参与事务 -->  <aop:config>   <aop:pointcut id="allManagerMethod" expression="execution(* org.springmore.core.dao..*(..))" />   <aop:advisor pointcut-ref="allManagerMethod" advice-ref="txAdvice" />  </aop:config>

dao代码示例：

@Repository("UserMapperImpl") public class UserMapperImpl implements UserMapper{    @Autowired  private DynamicSqlSessionTemplate sqlSessionTemplate;   //从库  public List<User> selectByUserNameAndPwd(User user) {   return sqlSessionTemplate.selectList("selectByUserNameAndPwd", user);  }   //主库  public void insert(User user) {    sqlSessionTemplate.insert("insert", user);    } }

springmore-redis组件

封装jedis客户端

使客户端调用更加简单
如：JedisTemplate负责对Jedis连接的获取与归还
分布式JedisShardedTemplate改用一致性哈希算法存取

JedisTemplate代码示例(用于非分布式部署的redis)初始化jedisTemplate，客户端可以将该部分代码封装到工厂类中

HostAndPort address = new HostAndPort("192.168.1.245",6380); JedisPoolConfig config = new JedisPoolConfig(); JedisPool jedisPool = new JedisDirectPool("pool", address, config); jedisTemplate = new JedisTemplate(jedisPool);

调用方法：JedisTemplate负责对Jedis连接的获取与归还

jedisTemplate.set("key", "value");

JedisShardedTemplate代码示例(用于分布式部署的redis)初始化JedisShardedTemplate

HostAndPort address1 = new HostAndPort("192.168.1.245",6380); HostAndPort address2 = new HostAndPort("192.168.1.246",6380); JedisPoolConfig config = new JedisPoolConfig(); JedisPool jedisPool1 = new JedisDirectPool("pool1", address1, config); JedisPool jedisPool2 = new JedisDirectPool("pool2", address2, config); jedisTemplate = new JedisShardedTemplate(new JedisPool[] { jedisPool1, jedisPool2 });

调用方法

jedisTemplate.set("key", "value");

springmore-commons组件

点击查看详细文档
这是一个工具类库包含如下功能

HttpClientUtil

功能：http以及https

基于最新的httpcomponents包实现

get请求，返回String报文，返回的报文默认是UTF-8编码

如果需要制定编码，可传入编码参数

@Test public void testDoGetStringString() throws Exception {  String doGet = HttpClientUtil.get("http://localhost:8888/login/");  String doGet2 = HttpClientUtil.get("http://localhost:8888/login/",HttpClientUtil.UTF_8);  System.out.println(doGet); }

post请求,可以制定编码

@Test public void testDoPost() throws Exception {  List <NameValuePair> nvps = new ArrayList <NameValuePair>();     nvps.add(new BasicNameValuePair("user.userName", "哈哈"));  String doGet = HttpClientUtil.post("http://localhost:8888/login/login!login.ac",nvps);  System.out.println(doGet); }

ssl请求

@Test public void testSSL() throws Exception {  String doGet = HttpClientUtil.getSSL("https://www.baidu.com", "utf-8");  List <NameValuePair> nvps = new ArrayList <NameValuePair>();     nvps.add(new BasicNameValuePair("user.userName", "哈哈"));  String post = HttpClientUtil.postSSL("https://www.baidu.com", nvps,"utf-8");  System.out.println(post); }

文件上传和下载

@Test public void getFile() throws Exception{  HttpClientUtil.getFile("http://localhost:8888/login/login!login.ac");  HttpClientUtil.postFile("http://localhost:8888/login/login!login.ac", "fileName", new File("d:/test.txt")); }
