我正在将我的应用程序 Web 逻辑移动到 Tomcat7



当应用程序在weblogic中运行时,下面的代码工作正常,但在tomcat中它给出了错误。主要问题是加载java:comp/env/jmx/runtime

因此,请让我知道我需要执行哪些配置才能在 tomcat 中运行代码。

我的代码:

    MBeanServer server = (MBeanServer)ctx.lookup("java:comp/env/jmx/runtime");
    // Get the Platform MBean Server
    ObjectName rs = new ObjectName("com.bea:Name=RuntimeService,Type=weblogic.management.mbeanservers.runtime.RuntimeServiceMBean");
    HashMap map = null;
    try
    {
        ObjectName domCfg = (ObjectName) server.getAttribute(rs,"DomainConfiguration");
        ObjectName[] jdbcSysResources =
        (ObjectName[]) server.getAttribute(domCfg, "JDBCSystemResources");
        map = new HashMap();
        for (int i=0 ; i<jdbcSysResources.length ; i++)
        {
            ObjectName jdbcResourceBean = (ObjectName) server.getAttribute(jdbcSysResources[i],"JDBCResource");
            ObjectName driverParamsBean =(ObjectName)server.getAttribute(jdbcResourceBean,"JDBCDriverParams");
            StringBuffer jdbcParams = new StringBuffer();
            ObjectName drvPropertiesBean = (ObjectName)server.getAttribute(driverParamsBean,"Properties");
            ObjectName[] drvProperties = (ObjectName[])server.getAttribute(drvPropertiesBean,"Properties");
            for(int j=0; j<drvProperties.length; j++)
            {
                String propName = (String)server.getAttribute(drvProperties[j],"Name");
                String propVal = (String)server.getAttribute(drvProperties[j],"Value");
                jdbcParams.append(propName).append("=").append(propVal).append(";");
            }
            String strTest = drvProperties.toString();
            ObjectName dsnParams =(ObjectName)server.getAttribute(jdbcResourceBean,"JDBCDataSourceParams"); 
            String[] dsnParamNames = (String[])server.getAttribute(dsnParams,"JNDINames");
            map.put(dsnParamNames[0].toString(),jdbcParams.toString());

Tomcat 不附带 JNDI 代理,不像 Weblogic。要使代码按原样工作,您需要添加一些 JNDI 提供程序。

我建议改用 DI。

Spring 框架可以做任何一个(例如)。

下面是一个示例
