cxf服务端设置字符编码

将{ MediaType.APPLICATION_JSON } 改为 { MediaType.APPLICATION_JSON + ";charset=UTF-8" }

@WebService
@Produces({ MediaType.APPLICATION_JSON + ";charset=UTF-8" })
@Consumes(MediaType.APPLICATION_JSON)
public class DemoWebServiceImpl implements DemoWebService { 
    ...
}

<bean id="demo" class="com.demo.webService.DemoWebServiceImpl"/>
<jaxrs:server id="demoWebService" address="/demo">
    <jaxrs:serviceBeans>
        <ref bean="demo"/>
    </jaxrs:serviceBeans>
</jaxrs:server>
