基于AOP和注释寻找方法参数​​的验证框架 [英] Looking for method argument validation framework based on AOP and annotations

问题描述

我在寻找参数验证框架：结果
1）允许通过指定annontations参数的约束（如椭圆形，JaValid）结果
2）验证code自动注入（编译或运行时）到方法中（即需要Validator对象没有显式调用）

I'm looking for argument validation framework which:
1) Allows specifying argument constraints via annontations (like OVal, JaValid)
2) Validation code automatically injected (during compilation or runtime) into methods (i.e. no explicit call to Validator object is required)

的例子就是我在寻找：

Example of what i'm looking for:

public class Person {
    private String name;
    ....
    //Method which arguments should be validated
    public void setName(@NotBlank String name){
        //<---validating code should be injected here
        this.name = name;
    }
} 

//Example of call to the validated method
...
    Person person = new Person();
    person.setName("John");
...

code我试图避免示例

Example of code i'm trying to avoid

...
    Validator validator = new Validator(...);//glue code
    Person person = new Person();
    person.setName("John");
    validator.validate(person);//glue code
...

谢谢解答！

推荐答案

我觉得你的意思是编译或运行时自动注入吧？

I think you meant "automatically injected during compilation or runtime", right?

我有同样的问题。我的解决办法是春天验证和自写AOP层（约三个等级）。

I had the same problem. My solution was Spring Validation and self-written AOP layer (about three classes).

我的验证code是这样的：

My validation code looks like this:

@Validational（验证=
  {com.mycompany.MyValidator}）

@Validational( validators = {"com.mycompany.MyValidator"} )

公共无效myMethod的（字符串paramToValidate）

public void myMethod( String paramToValidate )
