springboot开启gzip压缩

springboot 2.x开启gzip压缩

1.application.yml配置

复制代码

server:
  compression:
    enabled: true
    min-response-size: 1
    mime-types: application/json

2.代码设置（application.yml配置与代码设置二选一）

java 复制代码

@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(1);
            compression.setMinResponseSize(ds);
            servletContainer.setCompression(compression);
            //servletContainer.setPort(8088);
        }
    };
}

3.检查Content-Type一定是application/json

否则需要设置

java 复制代码

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