同学好，乱码就是由于编码不一致造成的，请检查你的spring-web.xml里面设置的utf-8

<!-- 配置SpringMVC -->
<!-- 1.开启SpringMVC注解模式 -->
<mvc:annotation-driven />
<!-- 2.静态资源默认servlet配置 (1)加入对静态资源的处理：js,gif,png (2)允许使用"/"做整体映射 -->
<mvc:resources mapping="/resources/**" location="/resources/" />
<mvc:default-servlet-handler />
<!-- 3.定义视图解析器 -->
<bean id="viewResolver"
class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<property name="prefix" value="/WEB-INF/html/"></property>
<property name="suffix" value=".html"></property>
</bean>
<!-- 文件上传解析器 -->
<bean id="multipartResolver"
class="org.springframework.web.multipart.commons.CommonsMultipartResolver">
<property name="defaultEncoding" value="utf-8"></property>
<!-- 1024 * 1024 * 20 = 20M -->
<property name="maxUploadSize" value="20971520"></property>
<property name="maxInMemorySize" value="20971520"></property>
</bean>
<!-- 4.扫描web相关的bean -->
<context:component-scan base-package="com.imooc.o2o.web" />
</beans>
还有html里面utf8
