springboot開啟gzip壓縮

 

springboot 2.x開啟gzip壓縮

1.application.yml配置

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

2.代碼設置（application.yml配置與代碼設置二選一）

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

3.檢查Content-Type一定是application/json

否則需要設置

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

4.檢查gzip是否起效
