使用JSR-303进行方法参数验证 [英] Method Parameter Validation with JSR-303

问题描述

JSR-303是否也用于方法参数验证?

Is JSR-303 also intended for method parameter validation?

如果是这样，网络上是否有任何示例?我面临的最大挑战是如何在每种方法中获取验证器.在Spring 3中，这是否意味着我实际上必须在每个类中注入LocalValidatorFactoryBean?

If so, is there any example on the web? The biggest challenge I'm facing is how to get a validator within each method. With Spring 3, doesn't it mean that I'd have to inject virtually every class with a LocalValidatorFactoryBean?

谢谢！

推荐答案

这听起来像是AOP(AspectJ)的用例.为用javax.validation.constraints.*注释的方法编写切入点，将验证器注入到方面(可能使用Spring)，并使用@Before或@Around建议在方法执行之前执行验证.

This sounds like a use case for AOP (AspectJ). Write a pointcut for methods that are annotated with javax.validation.constraints.*, inject a validator into the aspect (probably using Spring) and use a @Before or @Around advice to perform the validation before method execution.

阅读 AspectJ在行动中以供参考.
