web.xml ： Delegating（委托）Filter(过滤器) Proxy(代理) DelegatingFilterProxy委托过滤器代理

作用：拦截用户的请求，并把请求交给SpringSecurity来处理。

<filter>

<filter-name>springSecurityFilterChain</filter-name>
<filter-class>org.springframework.web.filter.DelegatingFilterProxy</filter-class>
</filter>
<filter-mapping>
<filter-name>springSecurityFilterChain</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>

springsecurity.xml

<security:http use-expressions="true" auto-config="true">

<security:intercept-url pattern="/**" access="hasRole('ROLE_ADMIN')"/>
</security:http>

    <!--配置密码加密对象-->
    <bean id="passwordEncoder"

    <!--开启注解方式权限控制-->
    <security:global-method-security pre-post-annotations="enabled" />
</beans>

最后一定要在controller中加入权限校验的注解
 @PreAuthorize("hasAuthority('CHECKITEM_DELETE')")

项目中的数据之类的调用如此,成功的话我们会接收到403错误,这样的话直接可以在前端页面接收进行判断

catch((error)=>{
    if(error=="Error: Request failed with status code 403"){
        this.$message.error("权限不足");
    }else{
        this.$message.error("网络异常，请重试");
    }
(我的前端使用的是Vue)
