Spring过滤器作为基于Java注释的bean

Question

我有一个Spring过滤器，格式如下XML

    <filter>
    <filter-name>SpringOpenEntityManagerInViewFilter</filter-name>
    <filter-class>org.springframework.orm.jpa.support.OpenEntityManagerInViewFilter</filter-class>
</filter>

<filter-mapping>
    <filter-name>SpringOpenEntityManagerInViewFilter</filter-name>
    <url-pattern>/*</url-pattern>
</filter-mapping>

我将其作为XML文件加载到类的顶部。有可能编写Java而不是XML定义吗

Answer 1

对于Spring，您应该定义一个扩展AbstractDispatcherServletInitializer的类，并向其添加以下行

@Override
protected Filter[] getServletFilters() {
    return new Filter[] {
        new OpenEntityManagerInViewFilter();
    };
}

您可以从Spring文档中获得有关Java代码中过滤器的更多信息 https://docs.spring.io/spring/docs/4.1.1.RELEASE/spring-framework-reference/html/mvc.html#mvc-container-config
