仅在 Spring Boot 中的请求日志 CommonsRequestLoggingFilter 之前设置

Question

CommonsRequestLoggingFilter在记录请求方面非常好，但就我而言，它在处理请求之前和之后记录相同的内容，这是重复且冗余的。我想摆脱请求后处理日志，但我找不到如何做到这一点。有任何想法吗？

import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.web.filter.CommonsRequestLoggingFilter;

@Configuration
public class RequestLoggingFilterConfig {

    @Bean
    public CommonsRequestLoggingFilter logFilter() {
        CommonsRequestLoggingFilter filter = new CommonsRequestLoggingFilter();
        filter.setIncludeClientInfo(true);
        filter.setIncludeHeaders(true);
        filter.setIncludePayload(false);
        filter.setIncludeQueryString(true);
        return filter;
    }
}

我从这里开始。

Answer 1

org.springframework.web.filter.CommonsRequestLoggingFilter类只是org.springframework.web.filter.AbstractRequestLoggingFilter的子类。因此，跳过 CommonsRequestLoggingFilter 并编写您自己的子类，并将覆盖的方法保留afterRequest()为空。

public class CustomizedRequestLoggingFilter extends AbstractRequestLoggingFilter {

    @Override
    protected void beforeRequest(HttpServletRequest httpServletRequest, String message) {
        this.logger.debug(message);
    }

    @Override
    protected void afterRequest(HttpServletRequest httpServletRequest, String message) {

    }
}

使用此类代替org.springframework.web.filter.CommonsRequestLoggingFilter

为了避免重复记录，在实例化时，CommonsRequestLoggingFilter您必须覆盖两者之一：

• beforeRequest()
• 请求后()

要禁用 afterRequest() 中的日志记录，可以更改 OP 的代码，如下所示：

import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.web.filter.CommonsRequestLoggingFilter;

@Configuration
public class RequestLoggingFilterConfig {

    @Bean
    public CommonsRequestLoggingFilter logFilter() {
        CommonsRequestLoggingFilter filter = new CommonsRequestLoggingFilter() {
            @Override
            public void afterRequest(HttpServletRequest request, String message) {
                // No body, we are just overriding the default behavior
            }
        };

        filter.setIncludeClientInfo(true);
        filter.setIncludeHeaders(true);
        filter.setIncludePayload(false);
        filter.setIncludeQueryString(true);
        return filter;
    }
}
