接口 JndiCallback<T>

类型参数:
T - the resulting object type
函数接口:
这是一个函数接口, 因此可用作 lambda 表达式或方法引用的赋值目标。
@FunctionalInterface public interface JndiCallback<T>
Callback interface to be implemented by classes that need to perform an operation (such as a lookup) in a JNDI context. This callback approach is valuable in simplifying error handling, which is performed by the JndiTemplate class. This is a similar to JdbcTemplate's approach.

Note that there is hardly any need to implement this callback interface, as JndiTemplate provides all usual JNDI operations via convenience methods.

      @Nullable T doInContext(Context ctx) throws NamingException
      Do something with the given JNDI context.

      Implementations don't need to worry about error handling or cleanup, as the JndiTemplate class will handle this.

      参数:
      ctx - the current JNDI context
      返回:
      a result object, or null
      抛出:
      NamingException - if thrown by JNDI methods
