Ext+json+jsp构建的动态树

树节点组合模型
package cn.com.jsnh.model.catalog;
public class TreeModel {
private String node;
private CatalogModel model;
public String getNode() {
return node;
}
public void setNode(String node) {
this.node = node;
}
public CatalogModel getModel() {
return model;
}
public void setModel(CatalogModel model) {
this.model = model;
}
}
栏目模型【实际的树节点】
package cn.com.jsnh.model.catalog;
public class CatalogModel {
private String id;
private String text;
private Boolean leaf;
private String cls;
private String action;
private String model;
public String getId() {
return id;
}
public void setId(String id) {
this.id = id;
}
public String getText() {
return text;
}
public void setText(String text) {
this.text = text;
}
public Boolean getLeaf() {
return leaf;
}
public void setLeaf(Boolean leaf) {
this.leaf = leaf;
}
public String getCls() {
return cls;
}
public void setCls(String cls) {
this.cls = cls;
}
public String getAction() {
return action;
}
public void setAction(String action) {
this.action = action;
}
public String getModel() {
return model;
}
public void setModel(String model) {
this.model = model;
}
}
