Spring Boot + Thymeleaf + Dandelion配置不起作用

Question

我正在将Spring Boot与Thymeleaf一起使用，现在我想添加Dandelion数据表，但是它不起作用。

这是我的Maven依赖项：

<parent>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-parent</artifactId>
    <version>1.2.1.RELEASE</version>
    <relativePath /> <!-- lookup parent from repository -->
</parent>
<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-data-jpa</artifactId>
</dependency>
<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-web</artifactId>
</dependency>
<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-thymeleaf</artifactId>
</dependency>
<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-websocket</artifactId>
</dependency>
<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-tomcat</artifactId>
    <scope>provided</scope>
</dependency>
<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-test</artifactId>
    <scope>test</scope>
</dependency>

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

我正在遵循本指南http://dandelion.github.io/dandelion/docs/installation/thymeleaf.html并配置了以下bean：

@SpringBootApplication
public class Application {

    public static void main(String[] args) {
        SpringApplication.run(Application.class, args);
    }

    @Bean
    public FilterRegistrationBean dandelion() {
        FilterRegistrationBean registrationBean = new FilterRegistrationBean();
        registrationBean.setFilter(new DandelionFilter());
        registrationBean.addUrlPatterns("/*");
        return registrationBean;
    }

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

    @Bean
    public ServletContextTemplateResolver defaultTemplateResolver() {
        ServletContextTemplateResolver resolver = new ServletContextTemplateResolver();
        resolver.setTemplateMode("HTML5");
        resolver.setPrefix("/WEB-INF/templates/");
        resolver.setSuffix(".html");
        resolver.setCharacterEncoding("UTF-8");
        resolver.setCacheable(false);

        SpringTemplateEngine engine = new SpringTemplateEngine();
        engine.setTemplateResolver(resolver);
        engine.addDialect(new DataTablesDialect());

        return resolver;
    }

}

我已经将此HTML进行了测试：

 <!doctype html> <html xmlns:th="http://www.thymeleaf.org" xmlns:ddl="http://github.com/dandelion"> <head> <link type="text/css" href="/stylesheets/dataTables.css" media="screen" rel="stylesheet" /> <script src="/javascripts/vendor/jquery191.js" type="text/javascript"></script> <script src="/javascripts/vendor/dataTables.js" type="text/javascript"></script> </head> <body> <br/> <table id="myTableId" ddl:table="true" ddl:url="@{/clientes}"> <thead> <tr> <th ddl:property="telefone">Telefone</th> <th ddl:property="nome">Nome</th> </tr> </thead> </table> </body> </html>

我认为未调用Dandelion的servlet。 命名空间未处理。 在此处输入图片说明

有几个错误。 它们中的大多数与我第一次使用蒲公英数据表时所做的相同。 :)

我正在为下面的每个代码编写完整的简单示例，以供将来任何人参考。 因此，请确保仅将丢失的项目添加到项目中

首先将这两个依赖项添加到您的Maven中。 （您已经有了第一个。因此添加后一个。）

<dependency>
    <groupId>com.github.dandelion</groupId>
    <artifactId>datatables-thymeleaf</artifactId>
    <version>0.10.1</version>
</dependency>
<dependency>
    <groupId>com.github.dandelion</groupId>
    <artifactId>datatables-spring3</artifactId>
    <version>0.10.1</version>
</dependency>

然后添加这些配置。 您必须为方言创建Bean。 我想你错过了。

@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/*");
    }
}

而且视图可以是这样的

<!DOCTYPE html>
<html xmlns:th="http://www.thymeleaf.org"
      xmlns:ddl="http://www.thymeleaf.org/dandelion"
      xmlns:dt="http://www.thymeleaf.org/dandelion/datatables">
<head lang="en"></head>
<body>
    <table id="myTableId"
        dt:table="true"
        dt:url="@{/clientes}"
        dt:serverside="true"
        dt:processing="true">
          <thead>
            <tr>
              <th dt:property="telefone">Telefone</th>
              <th dt:property="nome">Nome</th>
            </tr>
          </thead>
     </table>
</body>
</html>

在这里，您正在使用服务器端处理。 这要求您的控制器在/clientes上有一个映射，该映射返回DatatablesResponse

@Override
@RequestMapping(value = "/clientes")
@ResponseBody
public DatatablesResponse<MyObject> data(HttpServletRequest request){
    List<MyObject> myObjectList = ... //logic to fetch a list of objects

    DatatablesCriterias criterias = DatatablesCriterias.getFromRequest(request);
    DataSet<MyObject> dataSet = new DataSet<>(myObjectList, (long)myObjectList.size(), (long)myObjectList.size());
    return DatatablesResponse.build(dataSet, criterias);
}

MyObject是您要传递给蒲公英数据表的对象

public class MyObject {
    private String telefone;
    private String nome;

    public String getTelefone() {
        return telefone;
    }

    public void setTelefone(String telefone) {
        this.telefone = telefone;
    }

    public String getNome() {
        return nome;
    }

    public void setNome(String nome) {
        this.nome = nome;
    }
}
