Question

我有一个模特-

package com.somecompany.gis.businessmodel;

import javax.validation.constraints.Pattern;

public class SearchParameters {

//Check if a valid URL 

@Pattern(regexp = "(https?:\\/\\/(?:www\\.|(?!www))[a-zA-Z0-9][a-zA-Z0-9-]+[a-zA-Z0-9]\\.[^\\s]{2,}|www\\.[a-zA-Z0-9][a-zA-Z0-9-]+[a-zA-Z0-9]\\.[^\\s]{2,}|https?:\\/\\/(?:www\\.|(?!www))[a-zA-Z0-9]\\.[^\\s]{2,}|www\\.[a-zA-Z0-9]\\.[^\\s]{2,})")
String endPoint;

}

我有一个控制器端点-

@RequestMapping(value="/search",method=RequestMethod.POST)
public Map<String,Object> search(@Valid @RequestBody SearchParameters searchParameters){
    //Do something
}

我期望@Pattern介入，并为Jackson的Validation错误提供错误信息。但这没有发生。正则表达式仅接受有效的URL。我在做什么错了？

这些是我在项目中的依赖项

请通过以下方式进行检查：

@RequestMapping(value="/search",method=RequestMethod.POST)
public Map<String,Object> search(@Valid @RequestBody SearchParameters searchParameters, BindingResult bindingResult){

    if (bindingResult.hasErrors()) {
        return "errorPage";
    }
    //Do something
}

bindingResult对象，可用于和检索验证错误。
