## 环境 ##

*  tomcat8
 *  win10
 *  idea部署

## 问题描述 ##

向服务器上传文件报错，状态码405，400。  
**可能出现问题：**

*  tomcat不允许写入请求`a response status of 405 Method Not Allowed`;
 *  上传的文件出错，常见的是文件名无法解析中文
 *  上传的地址错误，拼错URL

## 解决方法 ##

1.  修改tomcat的web.xml配置文件，允许http请求方法写入文件  
    找到tomcat安装目录，修改conf文件夹下的web.xml文件。  
    ![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3dlaXhpbl80MzIxNzk0Mg_size_16_color_FFFFFF_t_70_pic_center]

<init-param>
                <param-name>readonly</param-name>
                <param-value>false</param-value>
    </init-param>

**参数释义：**  
如果运行环境readonly（只读），则tomcat会拒绝所有的HTTP的修改方法（如put，delete），默认为true。

1.  上传文件名引起的错误可以对文件名进行转码即可解决，可以先用非中文文件名的文件试一试。
2.  通过输出语句可以检测上传URL是否出错，纠错后再次尝试。
