这是一个解决方案，虽然可能不是最好的解决方案，但我的重点不是这个，只是为了通过错误，我在 Spring Boot 2.2.5.RELEASE 版本上启用了 AJP。添加这个：

((AbstractAjpProtocol) ajpConnector.getProtocolHandler()).setSecretRequired(false);

我的 AJP 配置完整课程：

package com.ssldemo.config;

import org.apache.catalina.connector.Connector;
import org.apache.coyote.ajp.AbstractAjpProtocol;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.boot.web.embedded.tomcat.TomcatServletWebServerFactory;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;

@Configuration
public class TomcatConfiguration {

    @Value("${tomcat.ajp.port}")
    int ajpPort;

    @Value("${tomcat.ajp.remoteauthentication}")
    String remoteAuthentication;

    @Value("${tomcat.ajp.enabled}")
    boolean tomcatAjpEnabled;

    @Bean
    public TomcatServletWebServerFactory servletContainer() {

        TomcatServletWebServerFactory tomcat = new TomcatServletWebServerFactory();
        if (tomcatAjpEnabled) {
            Connector ajpConnector = new Connector("AJP/1.3");
            ajpConnector.setPort(ajpPort);
            ajpConnector.setSecure(false);
            ajpConnector.setAllowTrace(false);
            ajpConnector.setScheme("http");
            ((AbstractAjpProtocol) ajpConnector.getProtocolHandler()).setSecretRequired(false);
            tomcat.addAdditionalTomcatConnectors(ajpConnector);
        }

        return tomcat;
    }

}

应用程序属性

server.port=8082
tomcat.ajp.port=9090
tomcat.ajp.remoteauthentication=false
tomcat.ajp.enabled=true
