找不到媒体类型的 Jersey MessageBodyWriter=text/html

Question

我打算用"Thymeleaf"来显示html，但是报错如下。使用的服务器是tomcat8。我的代码看起来像。

应用程序设置

@ApplicationPath("/service")
public class ApplicationSetting extends ResourceConfig {

    public ApplicationSetting() {

        packages(this.getClass().getPackage().getName());

        register(ThymeleafViewProcessor.class);

        register(LoggingFilter.class);
        System.out.println("ApplicationSetting ");

}

已经解决了。我修改的要点如下

    <init-param>
        <param-name>javax.ws.rs.Application</param-name>
        <param-value>com.abc.def.jersey_de.MyApplication</param-value>
    </init-param>
