如何在 Spring Boot WebApplication 中集成 Apache Tiles？

Question

我想在我的 spring 启动应用程序中添加 apache 磁贴。

就像我们在 application.properties 文件中配置前缀和后缀一样，我也想知道如何配置tiles.xml。

I have added maven dependency of apache tiles in POM.xml file, But when i am returning the name of the tile definition from my controller its giving 404 error.

这是我的 POM.xml 文件

    <!-- https://mvnrepository.com/artifact/org.apache.tiles/tiles-jsp -->
    <dependency>
        <groupId>org.apache.tiles</groupId>
        <artifactId>tiles-jsp</artifactId>
        <version>3.0.8</version>
    </dependency>

这是我的瓷砖。xml 文件

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE tiles-definitions PUBLIC  "-//Apache Software Foundation//DTD Tiles Configuration 
3.0//EN"  "http://tiles.apache.org/dtds/tiles-config_3_0.dtd">
<tiles-definitions>
<definition name="home-page"
    template="/WEB-INF/layout/layout.jsp">
    <put-attribute name="body" value="/WEB-INF/pages/landing-page.jsp" />
    <put-attribute name="script" value="" />
    <put-attribute name="stylesheet" value="" />
</definition>
</tiles-definitions>

这是我的 controller 方法

@Controller
public class LandingPage {

    @RequestMapping("/")
    public String landingPage() {
        return "home-page";
    }
}

这是我的 TilesConfig.java 文件

import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.web.servlet.view.UrlBasedViewResolver;
import org.springframework.web.servlet.view.tiles3.TilesConfigurer;
import org.springframework.web.servlet.view.tiles3.TilesView;

@Configuration
public class TilesConfig {
    @Bean
    public UrlBasedViewResolver viewResolver() {
        UrlBasedViewResolver tilesViewResolver = new 
        UrlBasedViewResolver();
        tilesViewResolver.setViewClass(TilesView.class);
    return tilesViewResolver;
}

@Bean
public TilesConfigurer tilesConfigurer() {
    TilesConfigurer tilesConfigurer = new TilesConfigurer();
    String[] tilesXml = { "WEB-INF/tiles.xml" };
    tilesConfigurer.setDefinitions(tilesXml);
    return tilesConfigurer;
   }
}

Answer 1

确保您拥有 static 资源并且视图位于正确的路径中。 您可以如下配置图块视图解析器。

@Bean
public UrlBasedViewResolver viewResolver() {
    UrlBasedViewResolver tilesViewResolver = new UrlBasedViewResolver();
    tilesViewResolver.setViewClass(TilesView.class);
    return tilesViewResolver;
}

@Bean
public TilesConfigurer tilesConfigurer() {
    TilesConfigurer tilesConfigurer = new TilesConfigurer();
    String[] tilesXml = { "WEB-INF/tiles.xml" };
    tilesConfigurer.setDefinitions(tilesXml);
    return tilesConfigurer;
}

您需要做的第一件事是在您的配置中使用@EnableWebMvc。我在下面的配置中添加了您可以尝试将以下配置添加到您的应用程序中吗

public class MvcWebApplicationInitializer 
      extends AbstractAnnotationConfigDispatcherServletInitializer {

  // Load database and spring security configuration
  @Override
  protected Class<?>[] getRootConfigClasses() {
    return new Class[] { WebAppInitializer.class};
  }

  // Load spring web configuration
  @Override
  protected Class<?>[] getServletConfigClasses() {
    return new Class[] { WebMvcConfig.class };
  }

  @Override
  protected String[] getServletMappings() {
    return new String[] { "/" };
  }

@Configuration
@EnableWebMvc
@ComponentScan(basePackages = { "your component scan packages" })
public class WebMvcConfig implements WebMvcConfigurer {

    /**
     * Initialise Tiles on application startup and identify the location of the tiles configuration file, tiles.xml.
     * 
     * @return tiles configurer
     */
    @Bean
    public TilesConfigurer tilesConfigurer() {
        final TilesConfigurer configurer = new TilesConfigurer();
        configurer.setDefinitions(new String[] { "WEB-INF/tiles.xml" });
        configurer.setCheckRefresh(true);
        return configurer;
    }

    /**
     * Introduce a Tiles view resolver, this is a convenience implementation that extends URLBasedViewResolver.
     * 
     * @return tiles view resolver
     */
    @Bean
    public TilesViewResolver tilesViewResolver() {
        final TilesViewResolver resolver = new TilesViewResolver();
        resolver.setViewClass(TilesView.class);
        return resolver;
    }

    @Override
    public void configureDefaultServletHandling(
      DefaultServletHandlerConfigurer configurer) {
        configurer.enable();
    }
}
