[quote]过滤器配置[/quote]

    }

    @Override
    public void doFilter(ServletRequest request, ServletResponse response, FilterChain chain) throws IOException, ServletException {
        ServletRequest requestWrapper = null;

        if(request instanceof HttpServletRequest) {
            if(((HttpServletRequest) request).getMethod().equalsIgnoreCase("post")) {
                requestWrapper = new MyHttpServletRequestWrapper((HttpServletRequest) request);

    @Override

    }

[quote]springboot 对过滤器的支持需要使用@ServletComponentScan相关注解[/quote]

@Configuration
@ComponentScan("com.nnk.upstream")
@EnableAutoConfiguration
@ImportResource("classpath:/context/bean.xml")
@ServletComponentScan
public class SampleIntegrationApplication extends SpringBootServletInitializer {
    public static final Logger LOGGER = Logger.getLogger(SampleIntegrationApplication.class);
    public static String IntanceKey;
    @Override
    protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
        return application.sources(SampleIntegrationApplication.class);
    }
  public static void main(String[] args) throws Exception {
  SpringApplication.run(SampleIntegrationApplication.class, args);
}
}

[quote]使用httpClient请求Url会发现无法获取到流数据，如果是contentType:application/x-www-form-urlencoded; charset=UTF-8但是如果是contentType:text/plain; charset=GBK则可以获取流数据。流数据只能被读取一次，而且跟请求类型有关系[/quote]
