springboot开启gzip压缩

springboot 2.x开启gzip压缩

1.application.yml配置

server:
  compression:
    enabled: true
    min-response-size:
    mime-types: application/json

2.代码设置（application.yml配置与代码设置二选一）

@Bean
    public WebServerFactoryCustomizer<ConfigurableWebServerFactory> webServerFactoryCustomizer() {
        return new WebServerFactoryCustomizer<ConfigurableWebServerFactory>() {
            @Override
            public void customize(ConfigurableWebServerFactory  servletContainer) {
                Compression compression = new Compression();
                compression.setEnabled(true);
                compression.setMimeTypes(new String[]{"application/json"});
                DataSize ds = DataSize.ofBytes();
                compression.setMinResponseSize(ds);
                servletContainer.setCompression(compression);
                //servletContainer.setPort();
            }
        };
    }

3.检查Content-Type一定是application/json

否则需要设置

response.setHeader("Content-Type", "application/json");

4.检查gzip是否起效

比较设置前和设置后的文件大小
