带有Spring5的Dandelion-Core 1.1.1版本？

标签： javascript requirejs thymeleaf dandelion

我有一个使用Spring io.spring.platform 1.0.1.RELEASE构建的Spring IO项目，该项目现在已经寿终正寝了。我非常成功地将thymeleaf-spring4以及dandelion-core 0.10.1和dandelion-thymeleaf 0.10.1一起用于处理JavaScript和CSS依赖项绑定。快进了4年，我试图将我的项目更新为Spring 5，无论是否安装了春季靴，而我的障碍之一是缺少一些示例，这些示例说明了如何使用更新的spring和thymeleaf框架配置蒲公英，我喜欢不够聪明，无法自行解决。自2015年以来没有更新，蒲公英项目似乎已经停滞不前。http://dandelion.github.io/blog/和https://github.com/dandelion/dandelion。我不确定这是不可能的，但是当我将spring4与蒲公英0.10.0一起使用时，我将spring上下文名称空间架构保持为3.2，而1.1.1样本仍全部基于spring3。因此，这可能意味着它从未在Spring 3之前进行过更新，但也可能只是其他一些处理AMD加载的方法，好像使用require.js可能已经使对蒲公英捆扎机的需求过时了，而我只是没有知道。

有人让蒲公英与spring5配合使用，可以说这是如何工作的吗？如果不需要，是否有其他方法来处理将复杂的JS包加载到呈现的模板中？我记得，在正常的AMD模式中无法使用require.js来限制使用百里香叶渲染的镜腿时加载哪些资源，因为必须将包含声明为标头的一部分。蒲公英负责捆绑包中的依赖关系和排序，并构建必需的包并适当地排序它们。尽管新的js和css内联解析看起来很方便https://www.baeldung.com/spring-thymeleaf-3，但仍然不能满足包含js库集的需求。任何意见，将不胜感激。

我一直在致力于将项目转换为纯Java配置，以解决已知的xml名称空间问题。但是尝试加载蒲公英方言时仍然出现此Java错误：

2019-07-08 16：56：56,898警告[RMI TCP Connection（3）-127.0.0.1] support.AbstractApplicationContext（AbstractApplicationContext.java:557）-上下文初始化期间遇到异常-取消刷新尝试：org.springframework .beans.factory.BeanCreationException：创建在类路径资源[com / srcsolutions / ecumcms / springJavaConfig / DandelionConfig.class]中定义的名称为“ dandelionDialect”的bean时出错：通过工厂方法实例化Bean失败；嵌套的异常是org.springframework.beans.BeanInstantiationException：无法实例化[com.github.dandelion.thymeleaf.dialect.DandelionDialect]：工厂方法'dandelionDialect'抛出了异常；嵌套的异常是java.lang.NoSuchMethodError：org.thymeleaf.dialect.AbstractDialect：方法（）V未找到 2019-07-08 16：56：56,902错误[RMI TCP连接（3）-127.0.0.1] servlet.FrameworkServlet（FrameworkServlet.java:533）-上下文初始化失败 org.springframework.beans.factory.BeanCreationException：创建在类路径资源[com / srcsolutions / ecumcms / springJavaConfig / DandelionConfig.class]中定义的名称为'dandelionDialect'的bean时出错：通过工厂方法实例化Bean失败；嵌套的异常是org.springframework.beans.BeanInstantiationException：无法实例化[com.github.dandelion.thymeleaf.dialect.DandelionDialect]：工厂方法'dandelionDialect'抛出了异常；嵌套的异常是java.lang.NoSuchMethodError：org.thymeleaf.dialect.AbstractDialect：方法（）V未找到     在org.springframework.beans.factory.support.ConstructorResolver.instantiate（ConstructorResolver.java:627）〜[spring-beans-5.1.6.RELEASE.jar：5.1.6.RELEASE]     在org.springframework.beans.factory.support.ConstructorResolver.instantiateUsingFactoryMethod（ConstructorResolver.java:456）〜[spring-beans-5.1.6.RELEASE.jar：5.1.6.RELEASE]

然后我有一些配置类：

package com.srcsolutions.ecumcms.springJavaConfig;

import com.github.dandelion.core.web.DandelionFilter;
import com.github.dandelion.thymeleaf.dialect.DandelionDialect;
import nz.net.ultraq.thymeleaf.LayoutDialect;
import org.springframework.beans.BeansException;
import org.springframework.context.ApplicationContext;
import org.springframework.context.ApplicationContextAware;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.web.servlet.config.annotation.EnableWebMvc;
import org.thymeleaf.extras.conditionalcomments.dialect.ConditionalCommentsDialect;
import org.thymeleaf.extras.springsecurity5.dialect.SpringSecurityDialect;
import org.thymeleaf.spring5.SpringTemplateEngine;
import org.thymeleaf.spring5.templateresolver.SpringResourceTemplateResolver;
import org.thymeleaf.spring5.view.ThymeleafViewResolver;
import org.thymeleaf.templatemode.TemplateMode;

import javax.servlet.Filter;

@Configuration
@EnableWebMvc
public class ThymeleafContextConfig implements  ApplicationContextAware {

    private ApplicationContext applicationContext;

    public void setApplicationContext(final ApplicationContext applicationContext)
            throws BeansException {
        this.applicationContext = applicationContext;
    }

    @Bean
    public SpringTemplateEngine templateEngine() {
        SpringTemplateEngine templateEngine = new SpringTemplateEngine();
        templateEngine.setTemplateResolver(templateResolver());
        templateEngine.addDialect(new LayoutDialect());
        templateEngine.addDialect(new DandelionDialect());
        templateEngine.addDialect(new ConditionalCommentsDialect());
        templateEngine.addDialect(new SpringSecurityDialect());

        // Enabling the SpringEL compiler with Spring 4.2.4 or newer can
        // speed up execution in most scenarios, but might be incompatible
        // with specific cases when expressions in one template are reused
        // across different data types, so this flag is "false" by default
        // for safer backwards compatibility.
        templateEngine.setEnableSpringELCompiler(false);
        return templateEngine;
    }

    @Bean
    public SpringResourceTemplateResolver templateResolver() {
        SpringResourceTemplateResolver templateResolver = new SpringResourceTemplateResolver();
        templateResolver.setApplicationContext(this.applicationContext);
        templateResolver.setPrefix("/WEB-INF/templates/");
        templateResolver.setSuffix(".html");
        // HTML is the default value, added here for the sake of clarity.
        templateResolver.setTemplateMode(TemplateMode.HTML);
        // Template cache is true by default. Set to false if you want
        // templates to be automatically updated when modified.
        templateResolver.setCacheable(true);
        return templateResolver;
    }


    @Bean
    public ThymeleafViewResolver viewResolver(){
        ThymeleafViewResolver viewResolver = new ThymeleafViewResolver();
        viewResolver.setTemplateEngine(templateEngine());
        // NOTE 'order' and 'viewNames' are optional
        viewResolver.setOrder(1);
    return viewResolver;
}


}

and : 

   package com.srcsolutions.ecumcms.springJavaConfig;

import javax.servlet.FilterRegistration;
import javax.servlet.ServletContext;
import javax.servlet.ServletException;
import javax.servlet.ServletRegistration;

import org.springframework.beans.BeansException;
import org.springframework.context.ApplicationContext;
import org.springframework.web.WebApplicationInitializer;
import org.springframework.web.context.ContextLoaderListener;
import org.springframework.web.context.support.AnnotationConfigWebApplicationContext;

import com.github.dandelion.core.web.DandelionFilter;
import com.github.dandelion.core.web.DandelionServlet;

public class ApplicationInitializer implements WebApplicationInitializer {

    private ApplicationContext applicationContext;

    public void setApplicationContext(final ApplicationContext applicationContext) throws BeansException {
        this.applicationContext = applicationContext;
    }


    @Override
    public void onStartup(ServletContext servletContext) throws ServletException {

        // Register the Web application context
        AnnotationConfigWebApplicationContext mvcContext = new AnnotationConfigWebApplicationContext();
        mvcContext.register(WebContextConfig.class);

        // Context loader listener
        servletContext.addListener(new ContextLoaderListener(mvcContext));

        // Register the Dandelion filter
        //FilterRegistration.Dynamic dandelionFilter = servletContext.addFilter("dandelionFilter", new DandelionFilter());
        //dandelionFilter.addMappingForUrlPatterns(null, false, "/*");


        // Register the Dandelion servlet
        ServletRegistration.Dynamic dandelionServlet = servletContext.addServlet("dandelionServlet", new DandelionServlet());
        dandelionServlet.setLoadOnStartup(2);
        dandelionServlet.addMapping("/dandelion-assets/*");
    }
}

`

所以我仍然不确定春季和蒲公英的组合是否完全兼容。现在，如果我注释掉templateEngine.addDialect（new DandelionDialect（））;，错误消失了，并且我能够获取要渲染的基本模板，但是未处理与蒲公英json资源文件的捆绑。
