java - 无法在 Tomcat 中连接 jmxmp

Question

在我的 spring + tomcat 解决方案中，我遇到了 jmxmp 连接问题。

我在 tomcat 中启用了 jmx + 添加了 jmxremote_optional.jar

这是manager.log

这是spring con.xml

                <property name="managedMethods">
                    <list>
                        <value>getVal</value>
                        <value>setVal</value>
                    </list>
                </property>
            </bean>
        </property>
        <property name="beans">
            <map>
                <entry key="bean:name=Test" value-ref="test"/>
            </map>
        </property>
    </bean>
</beans>

这是java bean

public class Test {
    private String val = "";
    public String getVal() {
        return val;
    }
    public void setVal(String v) {
        val = v;
    }
}

我会回答我自己的问题:)。

问题是，端口 9875(jmxmp 的默认端口)被另一个服务使用。希望它能帮助其他人并节省他的时间
