ssm框架插入mysql数据库中文乱码问题解决

1.      检查web.xml

<!-- 编码过滤器 -->

<filter>

<filter-name>encodingFilter</filter-name>

<filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>

<async-supported>true</async-supported>

<init-param>

<param-name>encoding</param-name>

<param-value>UTF-8</param-value>

</init-param>

</filter>

<filter-mapping>

<filter-name>encodingFilter</filter-name>

<url-pattern>/*</url-pattern>

</filter-mapping>

2.      检查建表脚本：

CREATE TABLE `t_user_info` (

`id` int(11) NOT NULL AUTO_INCREMENT,

`user_name` varchar(40) NOT NULL COMMENT ‘用户名‘,

`password` varchar(255) NOT NULL COMMENT ‘密码‘,

PRIMARY KEY (`id`)

) ENGINE=InnoDB DEFAULT CHARSET=utf8 COMMENT=‘用户信息表‘;

3.      检查项目工程及jsp/java/xml文件

4.      检查jdbc.properties

url=jdbc:mysql://localhost:3306/ssm?useUnicode=true&characterEncoding=UTF-8
