Spring mvc 4 javaConfig 配置 post 乱码问题：报错

public class XKingWebAppInitializer extends AbstractAnnotationConfigDispatcherServletInitializer{

	// 设置映射路径
	protected String[] getServletMappings() {
		// TODO Auto-generated method stub
		return new String[] {"/"};
	}

	// 指定配置类：RootConfig
	protected Class<?>[] getRootConfigClasses() {
		return new Class[] {RootConfig.class, SecurityConfig.class, MailConfig.class};
	}

	// 指定配置类：WebConfig
	protected Class<?>[] getServletConfigClasses() {
		return new Class[] {WebConfig.class};
	}
	
	@Override
	public void onStartup(ServletContext servletContext) throws ServletException {
		// TODO Auto-generated method stub
		super.onStartup(servletContext);
		servletContext.addFilter("name", new CharacterEncodingFilter("UTF-8", true))
			.addMappingForUrlPatterns(null, false, "/*");
	}
}

原来使用 Spring Security 时才有这个问题。

并且这设置时好时坏

最终的解决方案

public class SecurityWebInitializer extends AbstractSecurityWebApplicationInitializer{
	
    @Override
    protected void beforeSpringSecurityFilterChain(ServletContext servletContext) {
        FilterRegistration.Dynamic characterEncodingFilter = servletContext.addFilter("encodingFilter", new CharacterEncodingFilter());
        characterEncodingFilter.setInitParameter("encoding", "UTF-8");
        characterEncodingFilter.setInitParameter("forceEncoding", "true");
        characterEncodingFilter.addMappingForUrlPatterns(null, false, "/*");
    }   
}

已解决

如下设置，搞了一上午 

public class XKingWebAppInitializer extends AbstractAnnotationConfigDispatcherServletInitializer{

	// 设置映射路径
	protected String[] getServletMappings() {
		// TODO Auto-generated method stub
		return new String[] {"/"};
	}

	// 指定配置类：RootConfig
	protected Class<?>[] getRootConfigClasses() {
		return new Class[] {RootConfig.class, SecurityConfig.class, MailConfig.class};
	}

	// 指定配置类：WebConfig
	protected Class<?>[] getServletConfigClasses() {
		return new Class[] {WebConfig.class};
	}
	
	@Override
	public void onStartup(ServletContext servletContext) throws ServletException {
		// TODO Auto-generated method stub
		super.onStartup(servletContext);
		servletContext.addFilter("name", new CharacterEncodingFilter("UTF-8", true))
			.addMappingForUrlPatterns(null, false, "/*");
	}
}

谢谢！非常感谢！
