在配置里加個Filter：
<code>
@Bean
public FilterRegistrationBean filterRegistrationBean(){
FilterRegistrationBean registrationBean = new FilterRegistrationBean();
CharacterEncodingFilter characterEncodingFilter = new CharacterEncodingFilter();
characterEncodingFilter.setEncoding("UTF-8");
registrationBean.setFilter(characterEncodingFilter);
return registrationBean;
}
</code>
其次，需要在連接數據庫的url中增加一個GET參數：
<code>characterEncoding=utf8</code>
