关于SpringMVC乱码问题

关于SpringMVC运行Tomcat控制台出现乱码的情况(在网上找到一种方法亲测有效)

找到tomcat文件夹中的conf包下的logging.properties中找到

java.util.logging.ConsoleHandler.encoding = UTF-8

将这行代码注销改为

java.util.logging.ConsoleHandler.encoding = GBK

重启tomcat即可!

关于SpringMVC提交表单时,网页出现乱码情况,有两种解决方法

方法一(自定义过滤器):

 public class EncodingFilter implements Filter {
@Override
public void init(FilterConfig filterConfig) throws ServletException { } @Override
public void doFilter(ServletRequest servletRequest, ServletResponse servletResponse, FilterChain filterChain) throws IOException, ServletException {
servletRequest.setCharacterEncoding("utf-8");
servletResponse.setCharacterEncoding("utf-8"); filterChain.doFilter(servletRequest,servletResponse);
} @Override
public void destroy() { }
}

在web.xml中配置过滤器

     <filter>
<filter-name>encoding</filter-name>
<filter-class>com.kuang.filter.EncodingFilter</filter-class>
</filter>
<filter-mapping>
<filter-name>encoding</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>

注意点: / 与 /* 的区别

/ : 只匹配所有请求,不会去匹配jsp页面

/* : 匹配所有请求,包括jsp页面

方式二(SpringMVC自带的过滤器)

 <filter>
<filter-name>characterEncodingFilter</filter-name>
<filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>
<init-param>
<param-name>encoding</param-name>
<param-value>UTF-8</param-value>
</init-param>
</filter>
<filter-mapping>
<filter-name>characterEncodingFilter</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
