最终生成的菜单：
首先按需求定义了一个model.
package com.jxlt.db.parse;
import java.io.Serializable;
public class TreeModel implements Serializable {
private static final long serialVersionUID = 7896562831509010976L;
private String code;
private String title;
private String url;
private boolean leaf;
private int level;
/**
* @return Returns the leaf.
*/
public boolean isLeaf() {
return leaf;
}
/**
* @param leaf
* The leaf to set.
*/
public void setLeaf(boolean leaf) {
this.leaf = leaf;
}
/**
* @return Returns the title.
*/
public String getTitle() {
return title;
}
/**
* @param title
* The title to set.
*/
public void setTitle(String title) {
this.title = title;
}
/**
* @return Returns the url.
*/
public String getUrl() {
return url;
}
/**
* @param url
* The url to set.
*/
public void setUrl(String url) {
this.url = url;
}
/**
* @return Returns the code.
*/
public String getCode() {
return code;
}
/**
* @param code
* The code to set.
*/
public void setCode(String code) {
this.code = code;
}
/**
* @return Returns the level.
*/
public int getLevel() {
return level;
}
/**
* @param level
* The level to set.
*/
public void setLevel(int level) {
this.level = level;
}
}获取内容：

TreeModel model = new TreeModel();
model.setCode(code);
model.setTitle(title);
model.setUrl(
"m/content/" + code + ".html");
model.setLeaf(false);
model.setLevel(
code != null ? code.length() / 3 : 0);
list.add(model);
}
} catch (SQLException e) {
e.printStackTrace();
} finally {
// DataSourceUtils.close(rs);
// DataSourceUtils.close(st);
DataSourceUtils.close(conn);
}
return list;
}

}test 一下：
logger.debug("writing file:" +
GeneratorTree.TREE_FILE);
FileWriter writer =
new FileWriter(GeneratorTree.TREE_FILE);
writer.write(GeneratorTree.generator());
writer.flush();
writer.close();
logger.debug("end");菜单js样本
