SpringMVC给控制器添加自定义注解控制访问权限

1、创建自定义组件

package com.qingbo.ginkgo.annotation;

import java.lang.annotation.Documented;
import java.lang.annotation.ElementType;
import java.lang.annotation.Inherited;
import java.lang.annotation.Retention;
import java.lang.annotation.RetentionPolicy;
import java.lang.annotation.Target;

@Documented
@Inherited
@Retention(RetentionPolicy.RUNTIME)
@Target({ElementType.METHOD, ElementType.TYPE})
public @interface MenuO {
/** 菜单名称 */
String name();
/** 菜单Code */
String code();
/** 父菜单Code */
String parent() default "--";
/** 等级  */
int leven() default 1;
/** 事件类型link,affiliated  */
String clickType();
/** 菜单类型 */
String type();
/** 菜单权限类型 */
int power() default 0;
/** 排序 */
int order() default 999;
/** 图标 */
String iconCls();
/** 是否在列表显示0显示,1隐藏 */
int isShow() default 0;
/** 菜单的唯一标示**/
String iconName();
/** 备注 */
String remark() default "";
}

2.在Controller中使用该自定义注解

@RequestMapping("facade")
@MenuO(name="代理商管理",code="agent-facade",parent="information-manager",type = MenuType.TYPE_WEB,leven=1,clickType=MenuType.LEVEN_LINK,iconName="agent",remark="平台", iconCls = "icon-codepen",order=12)
public String facade(SystemUser systemUser, Model model, String vague, HttpServletRequest request){return ""}

3.创建拦截器获得所有注解，然后创建和修改注解数据

/**
*
*/
package com.qingbo.onem2.web;
import java.lang.reflect.Method;
import org.apache.commons.logging.Log;
import org.apache.commons.logging.LogFactory;
import org.dom4j.Document;
import org.springframework.beans.BeansException;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.beans.factory.config.BeanPostProcessor;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;

import com.qingbo.ginkgo.annotation.MenuO;
import com.qingbo.ginkgo.base.service.SystemAddressService;
import com.qingbo.ginkgo.common.util.Config;
import com.qingbo.ginkgo.common.util.SimpleLogFormater;
import com.qingbo.ginkgo.helper.XmlUtil;
import com.qingbo.onem2.dto.AddressStatic;
import com.qingbo.onem2.dto.BankBinStatic;
import com.qingbo.onem2.web.biz.BankBinBizService;
import com.qingbo.onem2.web.biz.SystemFunctionBizService;

/**
* 资源菜单，启动初始化
* 功能：自动读取<@Controller>层的<@Menu>注解，进行菜单的配置
* @author 贺亮
*
*/
public class MenuInitProcessor implements BeanPostProcessor{
private static Log log = LogFactory.getLog(MenuInitProcessor.class);

@Autowired private SystemFunctionBizService systemFunctionBizService;
@Autowired private SystemAddressService systemAddressService;
@Autowired private BankBinBizService bankBinBizService;

@Override
public Object postProcessBeforeInitialization(Object bean, String beanName)throws BeansException {
return bean;
}

@Override
public Object postProcessAfterInitialization(Object bean, String beanName)throws BeansException {
//如果注册的bean不属于Controller，直接跳出
if (!bean.getClass().isAnnotationPresent(Controller.class)) {
return bean;
}
//得到父地址映射
String urlMapping = null;
if(bean.getClass().isAnnotationPresent(RequestMapping.class)){
RequestMapping classMapping= bean.getClass().getAnnotation(RequestMapping.class);
urlMapping = classMapping.value()[0];
}
//得到Controller下的所有方法，判断是否有注册信息
Method[] methods = bean.getClass().getDeclaredMethods();
for(Method method:methods){
if(method.isAnnotationPresent(MenuO.class)){
//开始注册信息
MenuO menu = method.getAnnotation(MenuO.class);
//log.info(SimpleLogFormater.formatResult("----->Menu<----- register local menu : "+menu.name()+":"+urlMapping));
//得到子地址映射
if(method.isAnnotationPresent(RequestMapping.class)){
RequestMapping methodMapping= method.getAnnotation(RequestMapping.class);
if(urlMapping!=null){
this.systemFunctionBizService.insertLocalMenu(menu,urlMapping+"/"+methodMapping.value()[0]);
}else{
this.systemFunctionBizService.insertLocalMenu(menu,methodMapping.value()[0]);
}
}
}
}
//初始化静态字典
new AddressStatic(systemAddressService);
new BankBinStatic(bankBinBizService);
return bean;
}
}


4.配置拦截器

<!-- 启动执行事项 -->
<bean class="com.qingbo.onem2.web.MenuInitProcessor"></bean>
