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
