Spring支持两种不同的验证方法:Spring验证和JSR-303 bean验证.两者都可以通过定义一个Spring验证器来使用,该验证器委托给其他委托者,包括bean验证器.到现在为止还挺好.
但是当注释实际请求验证的方法时,这是另一个故事.我可以像这样注释
@RequestMapping(value = "/object", method = RequestMethod.POST)
public @ResponseBody TestObject create(@Valid @RequestBody TestObject obj, BindingResult result) {
或者像这样
@RequestMapping(value = "/object", method = RequestMethod.POST)
public @ResponseBody TestObject create(@Validated @RequestBody TestObject obj, BindingResult result) {
这里,@ Valid是javax.validation.Valid,而@Validated是org.springframework.validation.annotation.Validated.后者的文档说
JSR-303的变体有效,支持验证组的规范.设计方便使用Spring的JSR-303支持,但不支持JSR-303特定.
这没有多大帮助,因为它没有确切地说明它是如何不同的.如果有的话.两者似乎都对我很好.
我有以下控制器方法:
@RequestMapping(value="/map/update", method=RequestMethod.POST, produces = "application/json; charset=utf-8")
@ResponseBody
public ResponseEntityWrapper updateMapTheme(
HttpServletRequest request,
@RequestBody @Valid List<CompanyTag> categories,
HttpServletResponse response
) throws ResourceNotFoundException, AuthorizationException {
...
}
CompanyTag以这种方式定义:
public class CompanyTag {
@StringUUIDValidation String key;
String value;
String color;
String icon;
Icon iconObj;
public String getKey() {
return key;
}
public void setKey(String key) {
this.key = key;
}
...
}
问题是未触发验证,未验证CompanyTag列表,从不调用"StringUUIDValidation"验证器.
如果我删除了List并且只尝试发送一个CompanyTag,即代替:
@RequestBody @Valid List<CompanyTag> categories,
使用:
@RequestBody @Valid CompanyTag category,
它按预期工作,所以显然Spring不喜欢验证事物列表(尝试使用数组,但也没有用).
任何人都知道缺少什么？
我有
实体:
package org.ibp.soq;
public class MyEntity {
private String field1;
private String field2;
//..getters and setters
}
实体的验证者:
package org.ibp.soq;
import org.springframework.stereotype.Component;
import org.springframework.validation.Errors;
import org.springframework.validation.Validator;
@Component
public class MyEntityValidator implements Validator {
@Override
public boolean supports(Class<?> clazz) {
return MyEntity.class.equals(clazz);
}
@Override
public void validate(Object target, Errors errors) {
MyEntity myEntity = (MyEntity) target;
// Logic to validate my entity
System.out.print(myEntity);
}
}
和
具有批量PUT方法的REST控制器:
package org.ibp.soq;
import java.util.List;
import javax.validation.Valid;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.WebDataBinder;
import org.springframework.web.bind.annotation.InitBinder;
import …
