Spring启动响应压缩不工作

Question

我有一些javascript捆绑文件，非常大，大约1MB。我正在尝试使用yml文件中的以下应用程序属性打开响应压缩：

server.compression.enabled: true
server.compression.mime-types: application/json,application/xml,text/html,text/xml,text/plain,application/javascript,text/css

但不管用。没有压缩发生。

请求标题：

Connection: keep-alive
Pragma: no-cache
Cache-Control: no-cache
User-Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10_11_5) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/51.0.2704.103 Safari/537.36
Accept: */*
Accept-Encoding: gzip, deflate, sdch, br

Cache-Control:no-cache, no-store, max-age=0, must-revalidate
Connection:keep-alive
Content-Length:842821
Content-Type:application/javascript;charset=UTF-8

===编辑3===进一步遵循@Chimmi的建议。我已经在建议的地方设置了断点。对静态资源（js文件）的请求似乎从未在这些断点停止过。只有rest API请求才会这样做。对于这些请求，由于某种原因，内容长度为零，这导致跳过内容压缩。

由于@Chimmi的建议，我在O.S.B.a.W.ServerProperties的第180行设置了一个断点，它显示所有属性都设置好了，但不知何故服务器没有遵守这个设置...：（

资源服务器配置：

@Configuration
@EnableResourceServer
public class ResourceServerConfiguration extends ResourceServerConfigurerAdapter{

    @Autowired
    private TokenStore tokenStore;

    @Override
    public void configure(ResourceServerSecurityConfigurer resources)
            throws Exception {
        resources.tokenStore(tokenStore);
    }

    @Override
    public void configure(HttpSecurity http) throws Exception {
        // @formatter:off
        http.antMatcher("/**").authorizeRequests().antMatchers("/api/**").permitAll();
        // @formatter:on
    }
}

也许问题出在YAML配置上。如果您使用“starters”，SnakeYAML将通过spring-boot-starter自动提供。如果不这样做，则必须在application.properties中使用properties约定。使用YAML代替属性

编辑：在您的yml文件中尝试：

server:
      compression:
        enabled: true
        mime-types: text/html,text/xml,text/plain,text/css,application/javascript,application/json
        min-response-size: 1024
