abstract public String mappedName()
此 ejb 引用应该映射到的 EJB 组件的特定产品名称。此映射的名称通常是全局 JNDI 名称，但也可以是任何形式的名称。 应用服务器不需要支持任何特殊形式或类型的映射名称，也不需要具有使用映射名称的能力。映射的名称与产品有关，并且通常与安装有关。任何对映射名称的使用都不可移植。

mappedName

public abstract String mappedName

The product specific name of the EJB component to which this ejb reference should be mapped. This mapped name is often a global JNDI name, but may be a name of any form. Application servers are not required to support any particular form or type of mapped name, nor the ability to use mapped names. The mapped name is product-dependent and often installation-dependent. No use of a mapped name is portable.
