SSH-BOS项目：功能权限管理

FunctionAction：

package com.xushuai.bos.web.action;

import java.util.List;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.beans.factory.annotation.Qualifier;
import org.springframework.context.annotation.Scope;
import org.springframework.stereotype.Controller;

import com.xushuai.bos.entity.Function;
import com.xushuai.bos.service.FunctionService;
import com.xushuai.bos.utils.BOSUtils;

@Controller("functionAction")
@Scope("prototype")

	}
	public void setIds(String ids) {

	}

	/**
	 * 异步加载所有父节点
	 * @return
	 */
	public String ajaxList(){

	}
	
	/**

	 * @return
	 */
	public String add(){

	}
	
	/**
	 * 分页查询功能权限信息
	 * @return
	 */
	public String pageQuery(){
		/*
		 * 由于Fcuntion对象和分页参数中的page重名。
		 * 造成了分页参数无法正常接收，需要手动设置
		 */

		functionService.pageQuery(pageBean);
		BOSUtils.writerJson(pageBean, new String[]{"children","roles","currentPage","pageSize","criteria"});

	}

	 * @return
	 */
	public String delete(){

	/**
	 * 修改指定的权限信息
	 * @return
	 */
	public String edit(){

	}
	
}

FunctionService、FunctionServiceImpl：

package com.xushuai.bos.service;

import java.util.List;

import com.xushuai.bos.entity.Function;
import com.xushuai.bos.utils.PageBean;

public interface FunctionService {

	/**
	 * 加载所有权限信息
	 * @return
	 */
	List<Function> findAll();

	/**
	 * 新增功能权限
	 * @param model
	 */
	void save(Function model);

	/**
	 * 分页查询功能权限信息
	 * @param pageBean
	 */
	void pageQuery(PageBean pageBean);

	/**
	 * 删除指定功能权限(可以为多个)
	 * @param strings
	 */
	void delete(String[] ids);

	/**
	 * 修改指定的权限信息
	 * @param model
	 */
	void edit(Function model);

}

package com.xushuai.bos.service.impl;

import java.util.List;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.beans.factory.annotation.Qualifier;
import org.springframework.stereotype.Service;
import org.springframework.transaction.annotation.Transactional;

import com.xushuai.bos.dao.FunctionDao;
import com.xushuai.bos.entity.Function;
import com.xushuai.bos.service.FunctionService;
import com.xushuai.bos.utils.PageBean;

@Service("functionService")
@Transactional
public class FunctionServiceImpl implements FunctionService {
	
	@Autowired
	@Qualifier("functionDao")
	private FunctionDao functionDao;
	public void setFunctionDao(FunctionDao functionDao) {
		this.functionDao = functionDao;
	}


	@Override
	public List<Function> findAll() {
		return functionDao.findAll();
	}


	@Override
	public void save(Function model) {
		//健壮性校验
		Function parentFunction = model.getParentFunction();
		if(parentFunction != null && parentFunction.getId().equals("")){
			//如果父功能点ID为空字符串，将其设置为null
			model.setParentFunction(null);
		}
		functionDao.save(model);
	}


	@Override
	public void pageQuery(PageBean pageBean) {
		functionDao.findByPage(pageBean);
	}


	@Override
	public void delete(String[] ids) {
		Function function = null;
		for (String id : ids) {
			function = functionDao.findById(id);
			if(function != null)
				functionDao.delete(function);
		}
	}


	@Override
	public void edit(Function model) {
		Function _function = functionDao.findById(model.getId());
		if(_function != null){
			_function.setCode(model.getCode());
			_function.setDescription(model.getDescription());
			_function.setGeneratemenu(model.getGeneratemenu());
			_function.setName(model.getName());
			_function.setPage(model.getPage());
			_function.setParentFunction(model.getParentFunction());
			_function.setZindex(model.getZindex());
			//保存修改后的权限对象
			functionDao.save(_function);
		}
	}

}

FunctionDaoImpl（重写方法）：

	@Override
	public List<Function> findAll() {
		String hql = "FROM Function f WHERE f.parentFunction IS NULL";
		return (List<Function>) this.getHibernateTemplate().find(hql);
	}

Struts.xml（新增配置）：

		<!-- 功能权限管理模块 -->
		<action name="FunctionAction_*" class="functionAction" method="{1}">
			<result name="list">/WEB-INF/pages/admin/function.jsp</result>
		</action>

页面（funciton.jsp、function_add.jsp）：
