@ResponseBody 注解设置 utf-8 编码的方式

我最终采用的方式：

<bean class = "org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter">
<property name="messageConverters">
<array>
<bean class = "org.springframework.http.converter.StringHttpMessageConverter">
<property name="supportedMediaTypes" value = "text/plain;charset=UTF-8" />
</bean>
</array>
</property>
</bean>

在 stackoverflow 上还看到了另外的几种方式，但是没有尝试：
