如何设置Spring中每个错误字段中使用的全局前缀和后缀?

你为什么要这么做?Spring在内部呈现错误 <span> cssClass 属性 <spring:errors> 。然后,您可以通过CSS按自己的方式设置样式。

<跨度> customizable 同样,显然(我刚刚看了,从来没有需要自己改变它):

<spring:errors element="div" cssClass="errorBox" path="..."/>

将错误包装在 <div class="errorBox"></div>

有一个解决方法,但您必须实现自定义MessageSource

public class CustomMessageSource extends ResourceBundleMessageSource {

    private String prefix;
    private String suffix;

    public void setPrefix(String prefix) {
        this.prefix = prefix;
    }

    public void setSuffix(String suffix) {
        this.suffix = suffix;
    }

    public String getMessage(String code, Object[] args, String defaultMessage, Locale locale) {
        if(code.startsWith("typeMismatch"))
            return this.prefix + super.getMessage(resolvable, locale) + this.suffix;

        if(code.startsWith("errors"))
            return this.prefix + super.getMessage(resolvable, locale) + this.suffix;

        return super.getMessage(code, args, defaultMessage, locale);
    }

    public String getMessage(String code, Object[] args, Locale locale) throws NoSuchMessageException {
        if(code.startsWith("typeMismatch"))
            return this.prefix + super.getMessage(resolvable, locale) + this.suffix;

        if(code.startsWith("errors"))
            return this.prefix + super.getMessage(resolvable, locale) + this.suffix;

        return super.getMessage(code, args, locale);
    }

    public String getMessage(MessageSourceResolvable resolvable, Locale locale) throws NoSuchMessageException {
        String [] errors = resolvable.getCodes();
        for(String error: errors) {
            if(error.startsWith("typeMismatch"))
                return this.prefix + super.getMessage(resolvable, locale) + this.suffix;

            if(error.startsWith("errors"))
                return this.prefix + super.getMessage(resolvable, locale) + this.suffix;
        }

        return super.getMessage(resolvable, locale);
    }

}

<bean id="messageSource" class="br.com.some.CustomMessageSource">
    <property name="prefix" value="<div class=\"error\">"/>
    <property name="suffix" value="</div>"/>
    <property name="basenames">
        <list>
             <value>messages</value>
             <value>errors</value>
