blocks|key|2373926|text|您没有引用您的InnerObject类。您的控制器接受一个TestObject，但是类TestObject的字段"innerObject“是String类型。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|2373927|entityMap^0|0^^$0|@$1|2|3|4|5|6|7|D|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|E|8|@]|9|@]|A|$]]]|C|$]]

You are not referencing your InnerObject class. Your controller is taking a TestObject, but the field "innerObject" of the class TestObject is of type String.

blocks|key|2033197|text|好的，让我们再深入一点。我注意到我仍然在我的控制器中使用一个自定义验证器，如下所示：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|2033198|binder.setValidator(new+CustomValidator());|code-block|syntax|javascript|2033199|所以我删除了它，然后在内部对象的getter上方添加了@Valid，如下所示：|2033200|@Valid
public+InnerObject+getInnerObject();|2033201|现在我可以看到我的代码中有绑定错误。不过，我有一个新问题。我在BigDecimal属性上有@NotNull，并得到以下错误|2033202|org.springframework.web.util.NestedServletException:+Request+processing+failed;+nested+exception+is+javax.validation.UnexpectedTypeException:+No+validator+could+be+found+for+type:+java.math.BigDecimal|2033203|从文档中看，似乎支持BigDecimal。所以不确定到底是怎么回事。不过，我觉得我越来越接近了。|2033204|entityMap^0|0|0|0|0|0|0|0^^$0|@$1|2|3|4|5|6|7|S|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|T|8|@]|9|@]|A|$E|F]]|$1|G|3|H|5|6|7|U|8|@]|9|@]|A|$]]|$1|I|3|J|5|D|7|V|8|@]|9|@]|A|$E|F]]|$1|K|3|L|5|6|7|W|8|@]|9|@]|A|$]]|$1|M|3|N|5|D|7|X|8|@]|9|@]|A|$E|F]]|$1|O|3|P|5|6|7|Y|8|@]|9|@]|A|$]]|$1|Q|3|-4|5|6|7|Z|8|@]|9|@]|A|$]]]|R|$]]

Ok, getting a little further with this. I noticed that I was still using a custom validator in my controller like this:

<pre><code>binder.setValidator(new CustomValidator());
</code></pre>

So I removed it and then I added @Valid above the getter on my inner object like:

<pre><code>@Valid
public InnerObject getInnerObject();
</code></pre>

Now I can see that there are binding errors in my code. I have a new problem though. I have @NotNull on a BigDecimal property and I get the following error

<pre><code>org.springframework.web.util.NestedServletException: Request processing failed; nested exception is javax.validation.UnexpectedTypeException: No validator could be found for type: java.math.BigDecimal
</code></pre>

From the documentation it looks like BigDecimal is supported. So not sure what is going on. Think I am getting closer though.

blocks|key|2373950|text|确定以解决我更改的BigDecimal错误：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|2373951|private+BigDecimal+myField;|code-block|syntax|javascript|2373952|至|2373953|private+BigDecimal+myFeild+=+BigDecimal.Zero;|2373954|现在可以正常工作了。|2373955|唯一的缺点是，因为这些是我的表单支持对象，所以最初在字段中显示的是零而不是空白。|2373956|我不确定有没有办法解决这个问题？|2373957|entityMap^0|0|0|0|0|0|0|0^^$0|@$1|2|3|4|5|6|7|S|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|T|8|@]|9|@]|A|$E|F]]|$1|G|3|H|5|6|7|U|8|@]|9|@]|A|$]]|$1|I|3|J|5|D|7|V|8|@]|9|@]|A|$E|F]]|$1|K|3|L|5|6|7|W|8|@]|9|@]|A|$]]|$1|M|3|N|5|6|7|X|8|@]|9|@]|A|$]]|$1|O|3|P|5|6|7|Y|8|@]|9|@]|A|$]]|$1|Q|3|-4|5|6|7|Z|8|@]|9|@]|A|$]]]|R|$]]

Ok to resolve the BigDecimal error I changed:

<pre><code>private BigDecimal myField;
</code></pre>

to 

<pre><code>private BigDecimal myFeild = BigDecimal.Zero;
</code></pre>

It works properly now.

The only downside is that since these are my form backing objects a zero is displayed in the field initially instead of a blank.

I am not sure if there is any way around this?

I am trying to add validation to my model objects (which double as my form backing beans) using javax.validation annotations.

My model looks like this:

<pre><code>public Class TestObject {
 private String myProp;
 private InnerObject innerObject;

 //getters and setters omitted
}

public Class InnerObject {
 private BigDecimal myValue;

 @NotNull
 public BigDecimal getMyValue();
}
</code></pre>

In my controller I have the method call like this:

<pre><code>public View calculate(@ModelAttribute("testObject") @Valid TestObject testObject, BindingResult result)
</code></pre>

I also have the <code>&lt;mvc:annotation-driven/&gt;</code> in my spring-servlet.xml file.

Everytime I run the form with a null value it tells me there are 0 binding result errors.

I am using Java 1.6 with Hibernate-Validator-4.2.0 and Validation-API-1.0.0 on my classpath.

Can anyone help me and let me know what I am doing wrong? Been playing around with this for a while and can't get it to work.

Thanks
