我正在使用SpringBoot(2.1.3.release)和嵌入式tomcat(9.0.16版)开发一个java应用程序(jar文件)。
我想覆盖tomcat的catalina errorreportvalve错误页,
为此,我需要指示tomcat使用为此目的创建的自定义类,而不是默认类。这可以通过更新tomcat的配置文件“server.xml”中的host元素来实现。
自定义类:
import java.io.BufferedWriter;
import java.io.IOException;
import java.io.OutputStreamWriter;
import java.util.logging.Logger;
import org.apache.catalina.connector.Request;
import org.apache.catalina.connector.Response;
import org.apache.catalina.valves.ErrorReportValve;
public class CustomErrorReportValve extends ErrorReportValve {
// Create a simple logger
Logger log = Logger.getLogger(CustomErrorReportValve.class.getName());
@Override
protected void report(Request request, Response response, Throwable t) {
try {
// Write a more friendly, less technical message to the user
BufferedWriter out = new BufferedWriter(new OutputStreamWriter(response.getOutputStream()));
out.write("<html><head><title>Oops</title><body>");
out.write("<h1>Oops</h1>");
out.write("<p>Well, that didn't go as we had expected.</p>");
out.write("<p>Don't worry though, we're working on it.</p>");
out.write("</body></html>");
out.close();
// Log the error with your favorite logging framework...
log.severe("Uncaught throwable was thrown: " + t.getMessage());
} catch (IOException e) {
e.printStackTrace();
}
}
}
server.xml(或使用嵌入式tomcat时的tomcat-server.xml):
<Valve className="org.apache.catalina.valves.ErrorReportValve" showReport="false" showServerInfo="false" />
我在spring文档中发现,在spring中使用嵌入式tomcat时,配置文件名为tomcat-server.xml,而不是server.xml。
现在,问题是我在springboot项目中找不到tomcat-server.xml,或者如何配置/覆盖它,如果没有,是否有其他方法可以使用嵌入的tomcat在springboot中自定义catalina errorreportvalve错误页?
谢谢你的帮助!!
