Post request Filter use to solve the Chinese garbled

Post request Filter use to solve the Chinese garbled

First, create an interceptor to intercept all requests

@WebFilter(filterName = "login",
        dispatcherTypes = DispatcherType.REQUEST,
        urlPatterns = {"/*"})
public class LoginFilter implements Filter {
    @Override
    public void init(FilterConfig filterConfig) throws ServletException {

    }

    @Override
    public void doFilter(ServletRequest servletRequest, ServletResponse servletResponse, FilterChain filterChain) throws IOException, ServletException {
    }

    @Override
    public void destroy() {

    }
}

Second, the process unified response code

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