如何在Spring Boot中添加过滤器类？ [英] How to add a filter class in Spring Boot?

问题描述

我想知道，如果在Spring Boot中有一个 Filter 类的注释（对于Web应用程序）？也许 @Filter ？

我想在我的项目中添加自定义过滤器。

Spring Boot参考指南关于
FilterRegistrationBean

如果您想要设置第三方过滤器，您可以使用 FilterRegistrationBean 。
例如等效于web.xml

 < filter& 
< filter-name> SomeFilter< / filter-name> 
< filter-class> com.somecompany.SomeFilter< / filter-class> 
< / filter> 
< filter-mapping> 
< filter-name> SomeFilter< / filter-name> 
< url-pattern> / url / *< / url-pattern> 
< init-param> 
< param-name> paramName< / param-name> 
< param-value> paramValue< / param-value> 
< / init-param> 
< / filter-mapping> 
  

这些将是 @Configuration 文件

  @Bean 
 public FilterRegistrationBean someFilterRegistration（）{
 
 FilterRegistrationBean registration = new FilterRegistrationBean（）; 
 registration.setFilter（someFilter（））; 
 registration.addUrlPatterns（/ url / *）; 
 registration.addInitParameter（paramName，paramValue）; 
 registration.setName（someFilter）; 
 registration.setOrder（1）; 
退货注册; 
} 
 
 @Bean（name =someFilter）
 public Filter someFilter（）{
 return new SomeFilter（）; 
} 
  

上面是用spring-boot 1.2.3测试的

I wonder, if there is any annotation for a Filter class (for web applications) in Spring Boot? Perhaps @Filter?

I want to add a custom filter in my project.

The Spring Boot Reference Guide mentioned about FilterRegistrationBean, but I am not sure how to use it.

解决方案

If you want to setup a third-party filter you can use FilterRegistrationBean. For example the equivalent of web.xml

<filter>
     <filter-name>SomeFilter</filter-name>
        <filter-class>com.somecompany.SomeFilter</filter-class>
</filter>
<filter-mapping>
    <filter-name>SomeFilter</filter-name>
    <url-pattern>/url/*</url-pattern>
    <init-param>
       <param-name>paramName</param-name>
       <param-value>paramValue</param-value>
    </init-param>
</filter-mapping>

These will be the two beans in your @Configuration file

@Bean
public FilterRegistrationBean someFilterRegistration() {

    FilterRegistrationBean registration = new FilterRegistrationBean();
    registration.setFilter(someFilter());
    registration.addUrlPatterns("/url/*");
    registration.addInitParameter("paramName", "paramValue");
    registration.setName("someFilter");
    registration.setOrder(1);
    return registration;
} 

@Bean(name = "someFilter")
public Filter someFilter() {
    return new SomeFilter();
}

The above was tested with spring-boot 1.2.3
