java - spring responsebody 返回中文乱码

Answer 1

It also depends on what encoding your web container is... It will be over if you just step on it.

Answer 2

Encoding support for spring-mvc encoding adapter. I remember correctly that the tag name is:

<mvc:message-converters>

goods

Answer 3

1. spring mvc adds Jackson support

2. Add spring mvc configuration

<mvc:annotation-driven>
    <mvc:message-converters>
        <bean class="org.springframework.http.converter.StringHttpMessageConverter">
            <constructor-arg name="defaultCharset" value="UTF-8"/>
        </bean>
    </mvc:message-converters>
</mvc:annotation-driven>

Or override StringHttpMessageConverter

/* 将 */ public static final Charset DEFAULT_CHARSET = Charset.forName("ISO-8859-1");
/* 改 */ public static final Charset DEFAULT_CHARSET = Charset.forName("UTF-8");

Answer 4

Use other packet capture tools to test whether your return result is UTF-8 Chinese.
Problems often occur at the source or the last step.
If the page is garbled, your JSP page does not set charset "UTF-8".
If there are garbled characters in the browser console, use F12 Network and look at the response header Content-Type = text/html, Encoding and so on.
There is no problem with these links. It is probably a problem with the String environment settings. The previous answers are worth your reference.

Answer 5

When using springmvc to return the json format in the project, the Chinese characters were garbled. I looked at the springmvc source code and found that the default encoding of the StringHttpMessageConverter class is ISO-8859-1 (tragedy, why does something as big as springmvc not use utf-8, I don’t understand)

Here is the solution,

springmvc configuration file:

<bean class="org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter" >
        <property name="messageConverters">   
            <list>   
                <bean class = "org.springframework.http.converter.StringHttpMessageConverter">   
                    <property name = "supportedMediaTypes">
                        <list>
                            <value>text/html;charset=UTF-8</value>   
                        </list>   
                    </property>   
                </bean>   
            </list>   
        </property>  
    </bean>
    <bean class="org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerAdapter"> 
        <property name="messageConverters"> 
            <list>  
                <bean class="org.springframework.http.converter.StringHttpMessageConverter"> 
                    <property name="supportedMediaTypes"> 
                        <list> 
                            <value>text/html; charset=utf-8</value> 
                        </list> 
                    </property> 
                </bean>
            </list>  
        </property> 
    </bean>
    <bean class="org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerMapping">   
        <property name="interceptors">  
            <list>     
            </list>  
        </property>  
    </bean>  

To use this configuration, delete the in springmvc and do not use the default initialization configuration of springmvc

Answer 6

Have you added CharacterEncodingFilter? If you haven’t added it, try adding it. If it doesn’t work:
Which version of spirng and which version of tomcat are you using?
And:
It’s not as complicated as what’s said above. . . Looking at the pieces of xml is annoying. . .
