Java wildfly 8.2.0 oracle数据源

我对wildfly 8.2.0服务器中的oracle数据源有一些问题。我在域模式下使用服务器，带有两个服务器和具有默认配置文件的域控制器。因此，在我的域中，xml被声明为datasource和drivers

<datasource jta="true" jndi-name="java:jboss/datasources/mur-ng-mur" pool-name="mur-ng-mur" enabled="true" use-java-context="true" use-ccm="true">

尝试这样获取数据源。我假设您正在某个@Stateless bean中使用它

@PostConstruct
public void init() {
    String datasourceName = "java:jboss/datasources/mur-ng-mur";
    Context ctx;
    try {
        ctx = new InitialContext();
        dataSource = (DataSource) ctx.lookup(datasourceName);
        LOG.info("Datasource {} initialized", datasourceName);
    } catch (NamingException e) {
        LOG.error("ERROR reading datasource for name={}", datasourceName, e);
    }
}

异常涉及“jndiName=java:jboss/datasources/examples”。 您的问题必须位于代码的另一个位置。请尝试在项目中首先搜索示例

@PostConstruct
public void init() {
    String datasourceName = "java:jboss/datasources/mur-ng-mur";
    Context ctx;
    try {
        ctx = new InitialContext();
        dataSource = (DataSource) ctx.lookup(datasourceName);
        LOG.info("Datasource {} initialized", datasourceName);
    } catch (NamingException e) {
        LOG.error("ERROR reading datasource for name={}", datasourceName, e);
    }
}
