如何解决Spring MVC中响应乱码问题

    <!--启用包扫描-->
    <context:component-scan base-package="com.mufeng"/>

    <!--放行静态文件-->
    <mvc:default-servlet-handler/>
     <!--开启SpringMVC注解开发并解决乱码问题-->
    <mvc:annotation-driven>
        <mvc:message-converters>
            <bean class="org.springframework.http.converter.StringHttpMessageConverter">
                <property name="supportedMediaTypes">
                    <list>
                    <!--通过对StringHttpMessageConverter类的List做添加，修改响应的编码-->
                        <value>text/plain;charset=UTF-8</value>
                    </list>
                </property>
            </bean>
        </mvc:message-converters>
    </mvc:annotation-driven>

public abstract class AbstractHttpMessageConverter<T> implements HttpMessageConverter<T> {
	.....
	@Nullable
	private Charset defaultCharset;
	.....

    <!--解决乱码问题-->
    <mvc:annotation-driven>
        <mvc:message-converters>
            <bean class="org.springframework.http.converter.StringHttpMessageConverter">
                <property name="defaultCharset">
                    <value>UTF-8</value>
                </property>
            </bean>
        </mvc:message-converters>
