Spring Boot can use filters or interceptors to filter data.<\/p>\n

Using filters:<\/p>\n

    \n
  1. A Filter in javax.servlet<\/li>\n
  2. This is a component.<\/li>\n
  3. filter<\/li>\n
  4. carry out the filterChain<\/li>\n
  5. Please place an order.<\/li>\n<\/ol>\n

    Sample code:<\/p>\n

    @Component<\/span>\r\n@Order(1)<\/span>\r\npublic<\/span> class<\/span> MyFilter<\/span> implements<\/span> Filter<\/span> {\r\n    \r\n    @Override<\/span>\r\n    public<\/span> void<\/span> doFilter<\/span>(ServletRequest request, ServletResponse response, FilterChain chain)<\/span> throws<\/span> IOException, ServletException {\r\n        \/\/ \u8fdb\u884c\u8fc7\u6ee4\u64cd\u4f5c<\/span>\r\n        \/\/ ...<\/span>\r\n        \r\n        \/\/ \u5c06\u8bf7\u6c42\u4f20\u9012\u7ed9\u4e0b\u4e00\u4e2a\u8fc7\u6ee4\u5668\u6216\u76ee\u6807\u8d44\u6e90<\/span>\r\n        chain.doFilter(request, response);\r\n    }\r\n}\r\n<\/code><\/pre>\n
    Use interceptors.<\/p>\n
      \n
    1. Interceptor for handling requests<\/li>\n
    2. The component<\/li>\n
    3. handle before<\/li>\n
    4. truth<\/li>\n
    5. incorrect<\/li>\n
    6. @Request<\/li>\n<\/ol>\n
      Example code:<\/p>\n
      @Component<\/span>\r\n@Order(1)<\/span>\r\npublic<\/span> class<\/span> MyInterceptor<\/span> implements<\/span> HandlerInterceptor<\/span> {\r\n    \r\n    @Override<\/span>\r\n    public<\/span> boolean<\/span> preHandle<\/span>(HttpServletRequest request, HttpServletResponse response, Object handler)<\/span> throws<\/span> Exception {\r\n        \/\/ \u8fdb\u884c\u8fc7\u6ee4\u64cd\u4f5c<\/span>\r\n        \/\/ ...<\/span>\r\n        \r\n        \/\/ \u8fd4\u56detrue\u8868\u793a\u7ee7\u7eed\u6267\u884c\u540e\u7eed\u7684\u62e6\u622a\u5668\u6216\u5904\u7406\u5668\uff0c\u8fd4\u56defalse\u8868\u793a\u4e2d\u65ad\u540e\u7eed\u7684\u6267\u884c<\/span>\r\n        return<\/span> true<\/span>;\r\n    }\r\n}\r\n<\/code><\/pre>\n
      It is important to note that filters are based on the Servlet specification, allowing filtering operations on all requests, while interceptors are provided by the Spring MVC framework and can only filter requests for controllers.<\/p>\n","protected":false},"excerpt":{"rendered":"
