2.在DAO中使用
package com.lzw.dao;
import java.util.List;
import com.lzw.base.BaseDAO;
import com.lzw.pojo.Usertable;
public class UsertableDAO extends BaseDAO {
public static UsertableDAO INSTANCE = new UsertableDAO();
private UsertableDAO() {
}
public Usertable queryById(Integer id) {
return (Usertable) hibernateProxy.QueryById(Usertable.class, id);
}
public List<Usertable> findByPropertys(Object... propertys) {
return hibernateProxy.QueryByProperty(Usertable.TABLE_OBJECT_NAME,
propertys);
}
public List<Usertable> queryAll() {
return hibernateProxy.queryAll(Usertable.TABLE_OBJECT_NAME);
}
public void delete(Usertable usertable) {
hibernateProxy.delete(usertable);
hibernateProxy.evictObject(Usertable.class, usertable.getId());
}
public List executeByHqlForPage(int first, int max, Object... properties)
{
String hql = "from " + Usertable.TABLE_OBJECT_NAME;
return hibernateProxy.executeQueryByHqlForPage(hql, first, max, properties);
}
public boolean save(Usertable usertable) {
if (usertable.getId() != null) {
hibernateProxy.evictObject(Usertable.class, usertable.getId());
}
return hibernateProxy.save(usertable);
}
public boolean update(Usertable usertable) {
if (usertable.getId() != null) {
hibernateProxy.evictObject(Usertable.class, usertable.getId());
}
return hibernateProxy.update(usertable);
}
}

1.Hibernate的DAO封装

}
public List queryAll(String tableName) {

for (int i = 0; i < loopTime; i++) {
if (0 < i && i <= loopTime - 1) {
hqlRoot.append(" and ");
}
hqlRoot.append("model.");
hqlRoot.append(properties[i * 2]);
hqlRoot.append(" = ? ");
}
}
}
return hqlRoot.toString();
}
private List getQueryParameter(Object... propertys) {

}
}

1.简单国际化,获取资源改进,增加缓存
package com.lzw.action;
import java.io.IOException;
import java.io.InputStream;
import java.util.Collections;
import java.util.HashMap;
import java.util.Map;
import java.util.Properties;
import java.util.Map.Entry;
public class ResourceManager {
//资源缓存表
private Map<String, Properties> resourceMap = Collections
.synchronizedMap(new HashMap<String, Properties>());
public Properties getResource(String lang) throws IOException {
if (resourceMap.containsKey(lang))
{
return resourceMap.get(lang);
}
// ../../lang/lang_ZH_CN.properties
String langPath = "../../lang/lang_" + lang + ".properties";
Properties properties = this.getResourceByPath(langPath);
resourceMap.put(lang, properties);
return properties;
}
private Properties getResourceByPath(String path) throws IOException {
InputStream is = this.getClass().getClassLoader().getResourceAsStream(path);
Properties resource = new Properties();
resource.load(is);
is.close();
return resource;
}
/*
//使用
response.setCharacterEncoding("utf-8");
Properties resource = new ResourceManager().getResource("ZH_CN");
StringBuffer sb = new StringBuffer(500);
sb.append("<Res>\n");
for (Entry<Object, Object> entry : resource.entrySet())
{
//<key value = "123"/>
sb.append(" <" + entry.getKey() + " value=\"" + entry.getValue() + "\"/>" + "\n");
}
sb.append("</Res>");
response.getWriter().print(sb.toString());
return null;
*/
}

4.使用方法
<script type="text/javascript" src="common.js"></script>
<script type="text/javascript">
var resource = new ResourceMgr();
alert(resource.getResource("test"));
</script>
