Mysql允许远程访问

先修改/etc/init.d/my.cnf 下

bind-ipaddress = 0.0.0.0（原来是127.0.0.1）

Reference for all ips use below以下命令允许所有IP访问

GRANT ALL PRIVILEGES ON *.* TO 'myuser'@'%' WITH GRANT OPTION;

for particular ip use below以下命令只允许myuser用户通过youripaddres这个IP访问

java 文件夹下 Mybatis 的xml被IDE忽略 （可能会导致HTTP Status 500 - Request processing failed; nested exception is org.apache.ibatis.binding.BindingException: Invalid bound statement (not found): xxx）

首先要确定xml的路径是否正确配置

一种方法是

直接把mybatis的xml放到src/main/resources下

另外一种方法

在pom.xml中加：

<resource>
 ${basedir}/src/main/java

XMLHttpRequest cannot load http://XXX Origin http://XXX is not allowed by Access-Control-Allow-Origin.

参考

HttpServletResponse response = (HttpServletResponse) res;
response.setHeader("Access-Control-Allow-Origin", "*");
response.setHeader("Access-Control-Allow-Methods", "POST, GET, OPTIONS, DELETE");
response.setHeader("Access-Control-Max-Age", "3600");
response.setHeader("Access-Control-Allow-Headers", "这里写允许的头，比如Content-Type 等");
chain.doFilter(req, res);
