没有调用蒲公英Servlet答案

【问题标题】：DandelionServlet is not being invoked没有调用蒲公英Servlet
【发布时间】：2015-09-03 01:53:38
【问题描述】：

这是我的问题。我正在尝试在我的 Spring-boot Thymeleaf 应用程序上设置蒲公英数据表。我相信我已经正确连接了所有东西。我可以从日志中的 AssetCacheManger 获取 javascript 文件，并从 URL 手动调用 DandelionServlet，但它不会像 GitHub 上的示例那样自动调用。另请注意，我安装了 Spring Security。在发布之前，我禁用了安全性以确保这不是问题。

POM

<dependency> <groupId>com.github.dandelion</groupId> <artifactId>datatables-thymeleaf</artifactId> <version>0.10.0</version> </dependency>

JavaConfig

@Configuration
public class DandelionConfig
{
    @Bean
    public DandelionDialect dandelionDialect()
    {
        return new DandelionDialect();
    }

    @Bean
    public DataTablesDialect dataTablesDialect()
    {
         return new DataTablesDialect();
    }

    @Bean
    public FilterRegistrationBean dandelionFilterRegistrationBean()
    {
         FilterRegistrationBean filterRegistrationBean = new FilterRegistrationBean();
         DandelionFilter dandelionFilter = new DandelionFilter();
         filterRegistrationBean.setFilter(dandelionFilter);
         return filterRegistrationBean;
    }

    @Bean
    public ServletRegistrationBean dandelionServletRegistrationBean()
    {
         ServletRegistrationBean servletRegistrationBean = new ServletRegistrationBean();
         DandelionServlet dandelionServlet = new DandelionServlet();
         servletRegistrationBean.setServlet(dandelionServlet);
         servletRegistrationBean.addUrlMappings("/dandelion-assets/*");
         return servletRegistrationBean;
    }
 }

这里是不同于 GitHub 示例的日志部分。在 AssetMapper 上找不到委托的位置

参考这个答案

Spring Boot + Thymeleaf + Dandelion configuration not working

你能改用这个配置吗

@Configuration
public class DandelionConfig {

    @Bean
    public DandelionDialect dandelionDialect() {
        return new DandelionDialect();
    }

    @Bean
    public DataTablesDialect dataTablesDialect(){
        return new DataTablesDialect();
    }

    @Bean
    public Filter dandelionFilter() {
        return new DandelionFilter();
    }

    @Bean
    public ServletRegistrationBean dandelionServletRegistrationBean() {
        return new ServletRegistrationBean(new DandelionServlet(), "/dandelion-assets/*");
    }
}

连同这些依赖项

<dependency>
    <groupId>com.github.dandelion</groupId>
    <artifactId>datatables-thymeleaf</artifactId>
    <version>0.10.1</version>

【解决方案2】：

我使用 Thymeleaf 和 Dandelion-datatables 创建了一个简单的 Spring Boot 应用程序。
