Spring配置@ResponseBody JSON格式 [英] Spring configure @ResponseBody JSON format

问题描述

想象一下，我在Spring 3 @Controller中有这个带注释的方法

Imagine I have this annotated method in a Spring 3 @Controller

@RequestMapping("")
public @ResponseBody MyObject index(@RequestBody OtherObject obj) {
    MyObject result = ...;
    return result;
}

但我需要配置输出json格式，就像我在做：

But I need to configure the output json format, just as if I were doing:

ObjectMapper om = new ObjectMapper();
om.configure(JsonGenerator.Feature.QUOTE_FIELD_NAMES, true);
om.getSerializationConfig()
        .setSerializationInclusion(JsonSerialize.Inclusion.NON_DEFAULT);
om.getSerializationConfig()
        .set(SerializationConfig.Feature.INDENT_OUTPUT, false);

有没有办法配置这种行为？

Is there any way to configure this behaviour?

我发现了几个相关问题，但我不确定如何根据我的具体情况调整它们：

I've found a couple of related questions, but I am not sure about how to adapt them to my specific case:

1. spring prefixjson with responsebody


2. 在Spring MVC（@ResponseBody）中设置响应内容类型

1. spring prefixjson with responsebody
2. Who sets response content-type in Spring MVC (@ResponseBody)

谢谢！

AngerClown 向我指出了正确的方向。

AngerClown pointed me to the right direction.

这是我最终做的，以防万一有人发现它有用。

This is what I finally did, just in case anyone find it useful.

<bean
    class="org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter">
    <property name="messageConverters">
        <list>
            <bean class="org.springframework.http.converter.json.MappingJacksonHttpMessageConverter">
                <property name="objectMapper" ref="jacksonObjectMapper" />
            </bean>
        </list>
    </property>
</bean>

<!-- jackson configuration : https://stackoverflow.com/questions/3661769 -->
<bean id="jacksonObjectMapper" class="org.codehaus.jackson.map.ObjectMapper" />
<bean id="jacksonSerializationConfig" class="org.codehaus.jackson.map.SerializationConfig"
    factory-bean="jacksonObjectMapper" factory-method="getSerializationConfig" />
<bean
    class="org.springframework.beans.factory.config.MethodInvokingFactoryBean">
    <property name="targetObject" ref="jacksonSerializationConfig" />
    <property name="targetMethod" value="setSerializationInclusion" />
    <property name="arguments">
        <list>
            <value type="org.codehaus.jackson.map.annotate.JsonSerialize.Inclusion">NON_DEFAULT</value>
        </list>
    </property>
</bean>

我仍然需要弄清楚如何配置其他属性，例如：

I still have to figure out how to configure the other properties such as:

om.configure(JsonGenerator.Feature.QUOTE_FIELD_NAMES, true);
