在spring配置檔案中新增一下內容

<bean class="org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter">
    <property name="messageConverters">
        <list>
            <ref bean="mappingJackson2HttpMessageConverter" />
        </list>
    </property
 
>
</bean>
<bean id="mappingJackson2HttpMessageConverter"
    class="org.springframework.http.converter.json.MappingJackson2HttpMessageConverter">
    <property name="supportedMediaTypes">
        <list>
            <value>text/html;charset=UTF-8</value>
            <value>text/json;charset=UTF-8</value>
            <value>application/json;charset=UTF-8</value>
        </list>
    </property>
</bean>

java形式的配置

@Bean
public AnnotationMethodHandlerAdapter annotationMethodHandlerAdapter() {
    AnnotationMethodHandlerAdapter handlerAdapter = new AnnotationMethodHandlerAdapter();
    handlerAdapter.setMessageConverters(new HttpMessageConverter[]{jackson2HttpMessageConverter()});
    return handlerAdapter;
}

@Bean
public MappingJackson2HttpMessageConverter jackson2HttpMessageConverter(){
    MappingJackson2HttpMessageConverter messageConverter = new MappingJackson2HttpMessageConverter();
    List<MediaType> supportedMediaTypes = new ArrayList<MediaType>();
    supportedMediaTypes.add(MediaType.parseMediaType("text/html;charset=UTF-8"));
    supportedMediaTypes.add(MediaType.parseMediaType("text/json;charset=UTF-8"));
    supportedMediaTypes.add(MediaType.parseMediaType("application/json;charset=UTF-8"));
    messageConverter.setSupportedMediaTypes(supportedMediaTypes);
    return messageConverter;
}
