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
工具类这块，我希望越来越完善，如果大家有什么建议，或者补充的，尽管提出来，我尽量满足大家
真心希望得到大家的反馈

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

快速入门

		<property name="dataSource" ref="dataSource" />
	</bean>

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"));
}
