解决SpringMVC中文返回乱码的问题

1 在spring-mvc.xml增加

 <mvc:annotation-driven>
		<mvc:message-converters register-defaults="true">
			<!-- 将StringHttpMessageConverter的默认编码设为UTF-8 -->
			<bean class="org.springframework.http.converter.StringHttpMessageConverter">
		    	<constructor-arg value="UTF-8" />
			</bean>
		</mvc:message-converters>
	</mvc:annotation-driven>
