自动分配spring的bean名称以防止名称冲突? [英] Automatically assign spring's bean name to prevent name conflicts?
问题描述
在spring应用程序中，如果两个程序员开发两个包，将@Repository注释为相同的类名，则Spring会抛出"IllegalStateException":
In a spring app , if two programmers develop two packages , annotating @Repository to the same class name , Spring will throw "IllegalStateException" :
注释指定的Bean名称 'mybean'用于bean类 [foobar.package1.mybean]冲突 与现有的，不兼容的bean 相同名称和类别的定义 [foobar.package2.mybean]
Annotation-specified bean name 'mybean' for bean class [foobar.package1.mybean] conflicts with existing, non-compatible bean definition of same name and class [foobar.package2.mybean]
一种解决方案是在@Repository中添加额外的值，例如@Repository("package1.mybean")和@Repository("package2.mybean")，但是我正在寻找一种更有效的解决方案，该解决方案可以自动缓解这种情况.我希望该解决方案可以实现这些目标:
One solution is to add extra value in the @Repository , such as @Repository("package1.mybean") and @Repository("package2.mybean") , but I am looking for a more efficient solution , that can automatically ease such situation . I hope the solution can achieve these goals :
-
程序员可以在其程序包中随意命名其bean className，而不管其名称是否与其他程序包(程序员)冲突.这样程序员就不必大喊嘿，我将使用Bean名称XXXXX，不要与我冲突".
Programmers could arbitrarily name their bean className in his package , regardless of name conflicting with other packages(programmers). So that programmer doesn't need to yell 'Hey , I am going to use bean name XXXXX , don't conflict with me'.
没有手动分配XML Bean名称.
No manually XML bean name assign.
有什么想法吗?谢谢. (春季3)
Any ideas ? Thanks. (Spring 3)
推荐答案
在配置中的某些地方，您已经启用了类路径扫描，可能使用了
Somewhere in your config, you've enabled classpath scanning, probably using
<context:component-scan>
您可以指定一个名为name-generator的属性，该属性采用实现BeanNameGenerator接口的bean.创建您自己的接口实现，并提供对其的引用.
You can specify a property called name-generator, which takes a bean that implements the BeanNameGenerator interface. Create your own implementation of that interface and provide a reference to it.
