【Java】【Spring】SpringBoot中添加过滤器

添加一个过滤器，设置请求和响应编码为UTF-8

public class BaseFilter implements Filter {

    @Override
    @SneakyThrows
    public void doFilter(ServletRequest servletRequest, ServletResponse servletResponse, FilterChain filterChain) {
        HttpServletRequest request = (HttpServletRequest) servletRequest;

        //设置请求编码和响应编码
        request.setCharacterEncoding("UTF-8");
        servletResponse.setCharacterEncoding("UTF-8");

        filterChain.doFilter(request, servletResponse);
    }

    @Override
    public void init(FilterConfig config) {
    }

    @Override
    public void destroy() {
    }

}

在Application中注册此过滤器

@SpringBootApplication
public class AnimalApplication {

    public static void main(String[] args) {
        SpringApplication.run(AnimalApplication.class, args);
    }

    //添加一个基本过滤器，用于设置编码，调试观察请求数据
    @Bean
    public FilterRegistrationBean registerBaseFilter() {
        FilterRegistrationBean registration = new FilterRegistrationBean();
        registration.setFilter(new BaseFilter());
        registration.addUrlPatterns("/*");
        registration.setOrder(1);
        return registration;
    }

}
