我的问题是有时会正确提交UTF-8数据，但有时字符串会被破坏。
正确提交时，它看起来像这样：আনোয়ার/好/我是一个好男孩，但在提交不正确的时候，它看起来像：à|à|¨§§à§à||||||
UTF-8的数据库配置：
在MySql中：Charset：utf-8整理：utf8_general_ci
我的application.properties文件：
jdbc.driverClassName = com.mysql.jdbc.Driver
jdbc.url =jdbc:mysql://localhost:3306/icdb?useUnicode=true&characterEncoding=UTF-8&connectionCollation=utf8_general_ci&characterSetResults=utf8 jdbc.username = root
jdbc.password =password
hibernate.dialect = org.hibernate.dialect.MySQLDialect
hibernate.show_sql = true
hibernate.format_sql = true
这是我的SpringMvcInitializer类：
public class SpringMvcInitializer extends AbstractAnnotationConfigDispatcherServletInitializer {
@Override
public void onStartup(ServletContext servletContext) throws ServletException {
super.onStartup(servletContext);
FilterRegistration.Dynamic encodingFilter = servletContext.addFilter("encoding-filter", new CharacterEncodingFilter());
encodingFilter.setInitParameter("encoding", "UTF-8");
encodingFilter.setInitParameter("forceEncoding", "true");
encodingFilter.addMappingForUrlPatterns(null, false, "/*");
}
在控制器中：
@RequestMapping(value = "/saveNewOrder", produces = {"application/json; charset=UTF-8"}, method = RequestMethod.POST)
public String saveNewOrder(HttpServletRequest request, @Valid CatMenuSelection catMenuSelection, CatMenuSelectionExtra catMenuSelectionExtra, Model m, BindingResult result)
JSP文件如下所示：
<%@page contentType="text/html" pageEncoding="UTF-8"%>
<meta charset="utf-8"> <meta http-equiv="X-UA-Compatible" content="IE=edge">
<meta content="width=device-width, initial-scale=1, maximum-scale=1, user-scalable=no" name="viewport">

请帮助我找出总是无法插入utf-8数据的错误并获得解决方案。

我使用了以下代码，但它确实有效。
@Configuration
@EnableWebSecurity
public class SecurityConfiguration extends WebSecurityConfigurerAdapter{
@Override
protected void configure(HttpSecurity http) throws Exception {
CharacterEncodingFilter filter = new CharacterEncodingFilter();
filter.setEncoding("UTF-8");
filter.setForceEncoding(true);
http.addFilterBefore(filter, CsrfFilter.class);}

因此，您的问题与数据库配置无关。但实际上是弹簧配置问题。
然后，尝试在<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />标记中添加此<head>。并尝试将您的FilterRegistration更改为：
CharacterEncodingFilter ceFilter = new CharacterEncodingFilter();
ceFilter.setEncoding("UTF-8"); ceFilter.setForceEncoding(true);
FilterRegistration.Dynamic encodingFilter = servletContext.addFilter("encoding-filter", ceFilter);
如下面的评论所述。并且还要确保CharacterEncodingFilter是过滤器链中的第一个过滤器。
