Gradle plugin for Tomcat 9.0.34

Question

我正尝试使用https://github.com/bmuschko/gradle-tomcat-plugin.

我的渐变配置如下：

apply plugin: 'com.bmuschko.tomcat'
ext.tomcatVersion = '9.0.30'
dependencies {
// some dependencies
tomcat "org.apache.tomcat.embed:tomcat-embed-core:$tomcatVersion",
"org.apache.tomcat.embed:tomcat-embed-logging-juli:9.0.0.M6",
"org.apache.tomcat.embed:tomcat-embed-jasper:$tomcatVersion",
"org.apache.tomcat:tomcat-jdbc:$tomcatVersion",
"org.apache.tomcat:tomcat-dbcp:$tomcatVersion"
}
tomcat {
httpProtocol = 'org.apache.coyote.http11.Http11Nio2Protocol'
ajpProtocol  = 'org.apache.coyote.ajp.AjpNio2Protocol'
httpPort = 8088
}

Tomcat版本最高可达9.0.30，运行平稳，但对于最新的9.0.31+，会抛出以下异常(为简洁起见，请剪切(：

Caused by: java.lang.IllegalArgumentException: The AJP Connector is configured with secretRequired="true" but the secret attribute is either null or "". This combination is not valid.

如何摆脱它？这可以通过更改配置来解决吗？有没有任何tomcat插件叉可以很好地处理它，或者可能是tomcat的另一个gradle插件？

Answer 1

尝试更换

ajpProtocol  = 'org.apache.coyote.ajp.AjpNio2Protocol'

带有

ajpProtocol = 'org.apache.coyote.http11.Http11Nio2Protocol'

这将允许bmuschko绕过AJP连接器协议。
