带有Thymeleaf和Tomcat 8 UTF-8编码的Spring MVC问题 [英] Spring MVC with Thymeleaf and Tomcat 8 UTF-8 Encoding Issue

问题描述

我在编码方面有一些问题.根据此引用，我必须做所有这些事情，而且我做到了.但是在这些之后，我的编码问题仍然存在.我正在使用Spring MVC，Spring Security，Thymeleaf，Tomcat 8和Maven 3.

I have some problem about encoding. According to this referance I have to do all of this and I did. But my encoding problem still remain after those. I am using Spring MVC, Spring Security, Thymeleaf, Tomcat 8 and Maven 3.

这里有一些镜头.

我传递了带有模型的字符串，并且可以正常工作.

这是验证消息，来自我的message.properties文件.发生编码错误.

我正在尝试将一些记录保存到db，并且再次发生错误.

这就是我所做的.

我编辑了Tomcat的 server.xml 配置并添加了UTF-8编码.

I edited Tomcat's server.xml config and added UTF-8 encoding.

server.xml

  <Connector port="8080" protocol="HTTP/1.1"
           connectionTimeout="20000"
           useBodyEncodingForURI="true"
           URIEncoding="UTF-8"
           redirectPort="8443" />

我在配置文件夹中创建了 CharacterEncodingFilter .

I created CharacterEncodingFilter in my config folder.

CharacterEncodingFilter.java

@WebFilter(urlPatterns = {"/*"})
public class CharacterEncodingFilter implements Filter {

@Override
public void init(FilterConfig filterConfig)
        throws ServletException {

}

@Override
public void doFilter(ServletRequest servletRequest, ServletResponse servletResponse, FilterChain filterChain)
        throws IOException, ServletException {
    servletRequest.setCharacterEncoding("UTF-8");
    servletResponse.setContentType("text/html; charset=UTF-8");
    filterChain.doFilter(servletRequest, servletResponse);
}

@Override
public void destroy() {
}
}

我所有的html文件都有此meta标签行用于编码.

All my html files has this meta tag line for encoding.

    <meta http-equiv="Content-Type" content="text/html; charset=UTF-8">

我的Thymeleaf配置也设置为UTF-8编码.

My Thymeleaf configs are also set to UTF-8 encoding.

@Bean
@Description("Thymeleaf template resolver serving HTML 5")
public ServletContextTemplateResolver templateResolver() {
    ServletContextTemplateResolver templateResolver = new ServletContextTemplateResolver();
    templateResolver.setPrefix("/WEB-INF/html/");
    templateResolver.setSuffix(".html");
    templateResolver.setTemplateMode("LEGACYHTML5");
    templateResolver.setCharacterEncoding("UTF-8");
    templateResolver.setCacheable(false);

    return templateResolver;
}

@Bean
@Description("Thymeleaf template engine with Spring integration")
public SpringTemplateEngine templateEngine() {
    SpringTemplateEngine templateEngine = new SpringTemplateEngine();
    templateEngine.setTemplateResolver(templateResolver());

    return templateEngine;
}

@Bean
@Description("Thymeleaf view resolver")
public ThymeleafViewResolver viewResolver() {
    ThymeleafViewResolver viewResolver = new ThymeleafViewResolver();
    viewResolver.setTemplateEngine(templateEngine());
    viewResolver.setContentType("text/html;charset=UTF-8");
    viewResolver.setCharacterEncoding("utf-8");

    return viewResolver;
}

我用这样的UTF-8编码创建了数据库.

I created my database with UTF-8 encoding like this.

postgres=# CREATE USER unicodeuser WITH PASSWORD 'mypass123'; 
postgres=# CREATE DATABASE unicode WITH ENCODING 'UTF8' OWNER unicodeuser; 
postgres=# GRANT ALL ON DATABASE unicode TO unicodeuser;

我创建了JAVA_OPTS环境变量进行编码.

I created JAVA_OPTS environment variable for encoding.

JAVA_OPTS=-DuriEncoding=UTF-8 -Dfile.encoding=UTF-8

我也将 pom.xml 文件更改为UTF-8编码.

I also changed my pom.xml files for UTF-8 encoding.

<properties>
    <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
</properties>
...
<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-resources-plugin</artifactId>
    <version>2.7</version>
    <configuration>
        <encoding>UTF-8</encoding>
    </configuration>
 </plugin>

我尝试了Internet上的所有内容，但仍然找不到解决方案.关于我所缺少的任何想法都会很棒.

I tried everything on the internet but still can't find a solution. Any idea about what I am missing would be great.
