springmore-讓編程更容易

這是我多年項目的總結，並將其抽象出來，形成一個開源的項目
部分借鑒springside,將更多的實踐總結進來
基於spring+ibatis+springMVC
springmore-core專注於一些核心的應用，目前是讀寫分離組件
springmore-commons實用工具類
如：StringUtil,FileUtil,DateUtil,HTTPClientUtil,FTPUtil,DesUtil,ExcelUtil,XMLUtil等等
工具類這塊，我希望越來越完善，如果大家有什么建議，或者補充的，盡管提出來，我盡量滿足大家
真心希望得到大家的反饋

springmore-core

spring+ibatis實現讀寫分離

• 特點
  無縫結合spring+ibatis，對於程序員來說，是透明的
  除了修改配置信息之外，程序的代碼不需要修改任何東西
  支持spring的容器事務

• 規則:

1. 基於spring配置的容器事務
2. 讀寫事務到主庫
3. 只讀事務到從庫
4. 如果沒有配置事務，更新語句全部到主庫，查詢語句均衡到從庫

• 快速入門
  maven依賴

	@Autowired
	private DynamicSqlSessionTemplate sqlSessionTemplate;

	//從庫

springmore-redis組件

• 封裝jedis客戶端

1. 使客戶端調用更加簡單
   如：JedisTemplate負責對Jedis連接的獲取與歸還
2. 分布式JedisShardedTemplate改用一致性哈希算法存取

JedisTemplate代碼示例(用於非分布式部署的redis)
初始化jedisTemplate，客戶端可以將該部分代碼封裝到工廠類中

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

調用方法：JedisTemplate負責對Jedis連接的獲取與歸還

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

JedisShardedTemplate代碼示例(用於分布式部署的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 });

調用方法

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

springmore-commons組件

• 點擊查看詳細文檔
• 這是一個工具類庫 包含如下功能

HttpClientUtil

功能：http以及https
基於最新的httpcomponents包實現
get請求，返回String報文，返回的報文默認是UTF-8編碼
如果需要制定編碼，可傳入編碼參數

@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請求,可以制定編碼

@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請求

@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);
}	

文件上傳和下載

@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"));
