问题：Springboot3.0版本使用Tlog（1.5.1版本）开源框架时无法打印指定参数

原因：在Java EE 8及更高版本中，javax.servlet.*包已经替换成了jakarta.servlet.*，但是tlog官方只更新到了1.5.1版本所以还没支持到

解决方法：重写tlog中TLogServletFilter，TLogWebCommon两个关键类将javax.servlet包的东西替换成jakarta.servlet包的就可以了

话不多说，直接上代码

TLogServletFilter重写

import com.my.TLogWebCommon;
import com.yomahub.tlog.constant.TLogConstants;
import com.yomahub.tlog.context.TLogContext;import java.io.IOException;import jakarta.servlet.*;
import jakarta.servlet.http.HttpServletRequest;
import jakarta.servlet.http.HttpServletResponse;/*** 支持servlet* @author Bryan.Zhang* @since 1.3.5*/
public class TLogFilter implements Filter {@Overridepublic void init(FilterConfig filterConfig) throws ServletException {}//里面可以加入自定义的一些参数@Overridepublic void doFilter(ServletRequest request, ServletResponse response, FilterChain chain) throws IOException, ServletException {if (request instanceof HttpServletRequest && response instanceof HttpServletResponse){try{TLogWebCommon.loadInstance().preHandle((HttpServletRequest)request);//把traceId放入response的header，为了方便有些人有这样的需求，从前端拿整条链路的traceId((HttpServletResponse)response).addHeader(TLogConstants.TLOG_TRACE_KEY, TLogContext.getTraceId());chain.doFilter(request, response);return;}finally {TLogWebCommon.loadInstance().afterCompletion();}}chain.doFilter(request, response);}@Overridepublic void destroy() {}
}

TLogWebCommon类重写

import com.yomahub.tlog.constant.TLogConstants;
import com.yomahub.tlog.core.rpc.TLogLabelBean;
import com.yomahub.tlog.core.rpc.TLogRPCHandler;
import jakarta.servlet.http.HttpServletRequest;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;/*** TLog web这块的逻辑封装类*/
public class TLogWebCommon extends TLogRPCHandler {private final static Logger log = LoggerFactory.getLogger(TLogWebCommon.class);private static volatile TLogWebCommon tLogWebCommon;public static TLogWebCommon loadInstance() {if (tLogWebCommon == null) {synchronized (TLogWebCommon.class) {if (tLogWebCommon == null) {tLogWebCommon = new TLogWebCommon();}}}return tLogWebCommon;}public void preHandle(HttpServletRequest request) {String traceId = request.getHeader(TLogConstants.TLOG_TRACE_KEY);String spanId = request.getHeader(TLogConstants.TLOG_SPANID_KEY);String preIvkApp = request.getHeader(TLogConstants.PRE_IVK_APP_KEY);String preIvkHost = request.getHeader(TLogConstants.PRE_IVK_APP_HOST);String preIp = request.getHeader(TLogConstants.PRE_IP_KEY);TLogLabelBean labelBean = new TLogLabelBean(preIvkApp, preIvkHost, preIp, traceId, spanId);processProviderSide(labelBean);}public void afterCompletion() {cleanThreadLocal();}
}

注册自己写的过滤器

@Configuration
@ComponentScan(value = "com.yomahub.tlog")
public class LogConfig {@Beanpublic FilterRegistrationBean<TLogFilter> loggingFilter() {FilterRegistrationBean<TLogFilter> registrationBean = new FilterRegistrationBean<>();registrationBean.setFilter(new TLogFilter());registrationBean.addUrlPatterns("/*"); // 拦截所有请求路径return registrationBean;}
}
