java - SpringMVC@ResponseBody中文乱码

Answer 1

Just add this to the xml file
<mvc:annotation-driven>

    <mvc:message-converters register-defaults="true">
        <bean class="org.springframework.http.converter.StringHttpMessageConverter">
            <property name="supportedMediaTypes" value="text/html;charset=UTF-8"></property>
        </bean>
    </mvc:message-converters>
</mvc:annotation-driven>

Answer 2

I don’t know what MediaType is, but I have always used the encoding produces = "application/json;charset=UTF-8", or the front-end encoding is not utf-8

Answer 3

If the server is Tomcat, change to version 8.0 or above. Older versions did not encode UTF-8 by default.

Answer 4

Configure a spring encoding filter
I searched for one for reference
If it is a new project, check out spring boot. Basically, there is no need to configure it. Things like Chinese garbled characters are all configured by default.

Answer 5

Let’s talk about the garbled code problem GET and POST
POST configure the spring filter in the web. URIencoding=utf-8 or take it and use ISO-8859-1 to manually decode it and then encode it in UTF-8

Answer 6

Configuring a simple CharacterFilter may not solve the problem. If you are using Jackson2, try the following solution

<mvc:annotation-driven>
        <mvc:message-converters>
            <bean class="org.springframework.http.converter.json.MappingJackson2HttpMessageConverter">
                <property name="supportedMediaTypes">
                    <util:list>
                        <value>application/json;charset=UTF-8</value>
                        <value>text/html;charset=UTF-8</value>
                    </util:list>
                </property>
            </bean>
        </mvc:message-converters>
    </mvc:annotation-driven>

Jackson1 is the same, but the class is changed to MappingJacksonHttpMessageConverter
