消息转换器

1.消息转换器pom.xml的引入依赖。

<dependency>
  <groupId>org.hibernate</groupId>
  <artifactId>hibernate-validator</artifactId>
  <version>5.0.2.Final</version>
</dependency>

2.spring-mvc.xml中的配置：

     <!--消息转换器-->

   <mvc:annotation-driven validator="validator">
    <mvc:message-converters register-defaults="true">
        <bean       class="org.springframework.http.converter.StringHttpMessageConverter">
            <constructor-arg value="UTF-8"/>
            <property name="supportedMediaTypes">
                <list>
                    <value>text/plain;charset=UTF-8</value>
                    <value>text/html;charset=UTF-8</value>
                </list>
            </property>
        </bean>
    </mvc:message-converters>
</mvc:annotation-driven>

<bean id="validator" class="org.springframework.validation.beanvalidation.LocalValidatorFactoryBean">
    <property name="providerClass" value="org.hibernate.validator.HibernateValidator"/>
</bean>
