摘要: 许多spring mvc 项目都是通过在后台Java代码类方法的头部加入requestmapping实现前台到后台的通信，其实可以更进一步。
不善于写博客，第一篇，介绍下spring强大的类名加方法名实现极度简洁的mvc。正文如下：
1：对web项目加入spring支持，不罗嗦哪些jar包依赖了，仅仅展示web.xml的spring支持配置

上面是核心配置，这样就可以一步到位的去请求后台Java代码啦。
代码部分
实现一个简单的form tree加载，方法不全，仅仅演示使用
@Controller("formAction")
public class FormActionController extends AbstractActionController {
public void tree(HttpServletRequest req, HttpServletResponse resp) throws Exception {
StringBuffer buff = new StringBuffer("[");
ArrayList<Object> params = new ArrayList<Object>();
StringBuffer sql = new StringBuffer( "SELECT F.NAME,F.AD_FORM_ID FROM AD_FORM F WHERE 1=1 AND PARENTID IS NULL AND F.UPDATED >= TO_DATE('2013-04-08','YYYY-MM-DD') ORDER BY F.AD_FORM_ID ");
String sqls = sql.toString();
SqlRowSet rs = getJdbcTemplate().queryForRowSet(sqls, params.toArray());
while (rs.next()) {
buff.append("{id:'" + rs.getInt("AD_Form_ID")).append("',text:'" + rs.getString("Name")).append("',");
int id = rs.getInt("AD_Form_ID");
buff.append(childNode(id));
}
if (rs.isAfterLast()) {
buff.deleteCharAt(buff.length() - 1);
}
buff.append("]");
sendJSON(resp, buff.toString());
}
}
上面的controller只有一个注解 @Controller("formAction")
用于与前台界面进行URL路径匹配。
js
Ext.namespace("App.Form");
App.Form.Manager = function(config) {
config = config || {};
this.moduleId = config.moduleId || 'Form_Manager';
this.action = App.getContextPath() + "formAction";
var pageSize = App.getPageSize();
// 树菜单
var root = new Ext.tree.AsyncTreeNode({
id : '0',
text : "菜单列表",
draggable : false,
leaf : false,
expanded : true
});
var treeloader = new Ext.tree.TreeLoader({
dataUrl : this.action + "/tree.do"
});
var treepanel = new Ext.tree.TreePanel({
rootVisible : true,
hideCollapseTool : true,
collapsible : false,
id : this.moduleId + "_formTree",
width : 200,
minSize : 180,
maxSize : 250,
split : true,
autoHeight : false,
autoScroll : true, // 自动滚动
// containerScroll : true,// 是否支持滚动条
// border : true, // 边框
animate : true, // 动画效果
loader : treeloader,
lines : true,
trackMouseOver : true,
root : root,
listeners : {
scope : this,
"click" : function(node, event) {
node.expand();
var grid = Ext.getCmp(this.moduleId + "_treeGrid");
if (node.isLeaf()) {
return;
}
if (!node.isLeaf() && node.parentNode.id == 0) {
grid.getStore().reload({
params : {
parentID : node.id
}
})
}
}
}
});
}
在js中约束好对应名称即可 this.action = App.getContextPath() + "formAction";
请求方法如下：
dataUrl : this.action + "/tree.do"
这样就实现了完全的spring mvc 无需任何额外的配置啦。
