spring - 将 spring boot war 生成的文件部署到 tomcat 服务器，TemplateResolver 未定位文件

Question

我正在开发一个 Spring boot web 应用程序，当我这样运行它时一切都运行良好

java -Xdebug -Xrunjdwp:server=y,transport=dt_socket,address=8000,suspend=n -jar build/libs/MobileQuestionnaire-0.1.0.jar

但是如果我尝试将 war 部署到 Tomcat 8，它会正确加载，但我认为我的“TemplateResolver”bean 有问题。这是我的 MVC 配置文件:

@Configuration
@ComponentScan({"controler","data.service"})
@EnableTransactionManagement
@EnableJpaRepositories(basePackages = { "data.dao.repository" })
@EntityScan(basePackages = { "data.domain" })
@PropertySource("classpath:properties\\config.properties")
public class MvcConfig extends WebMvcConfigurerAdapter {

    @Autowired
    Environment env;

    private static String[] CLASSPATH_RESOURCE_LOCATIONS = { 
        "classpath:/META-INF/resources/", 
        "classpath:/static/", 
        "classpath:/public/" };

    @Bean
    public static PropertySourcesPlaceholderConfigurer propertySourcesPlaceholderConfigurer() {
        return new PropertySourcesPlaceholderConfigurer();
    }

    @Bean(name = "DataSource")
    public DriverManagerDataSource dataSource() {
        DriverManagerDataSource driverManagerDataSource = new DriverManagerDataSource();
        driverManagerDataSource.setDriverClassName(env.getProperty("database.driverManagerDataSource.setDriverClassName"));
        driverManagerDataSource.setUrl(env.getProperty("database.driverManagerDataSource.setUrl"));
        driverManagerDataSource.setUsername(env.getProperty("database.driverManagerDataSource.setUsername"));
        driverManagerDataSource.setPassword(env.getProperty("database.driverManagerDataSource.setPassword"));
        return driverManagerDataSource;
    }

    @Bean
    public EntityManagerFactory entityManagerFactory() {

        HibernateJpaVendorAdapter vendorAdapter = new HibernateJpaVendorAdapter();
        vendorAdapter.setGenerateDdl(true);

        LocalContainerEntityManagerFactoryBean factory = new LocalContainerEntityManagerFactoryBean();
        factory.setJpaVendorAdapter(vendorAdapter);
        factory.setPackagesToScan("data.domain", "data.dao.Repository");
        factory.setDataSource(dataSource());
        factory.afterPropertiesSet();

        return factory.getObject();
    }

    @Bean
    public PlatformTransactionManager transactionManager(EntityManagerFactory emf) {
        JpaTransactionManager transactionManager = new JpaTransactionManager();
        transactionManager.setEntityManagerFactory(emf);

        return transactionManager;
    }

    @Bean
    public PersistenceExceptionTranslationPostProcessor exceptionTranslation() {
        return new PersistenceExceptionTranslationPostProcessor();
    }

    public Properties additionalProperties() {
        Properties properties = new Properties();
        properties.setProperty("hibernate.hbm2ddl.auto", "create-drop");
        properties.setProperty("hibernate.dialect", "org.hibernate.dialect.MySQL5Dialect");
        return properties;
    }

    @Override
    public void addResourceHandlers(ResourceHandlerRegistry registry) {
        registry.addResourceHandler("/**").addResourceLocations(CLASSPATH_RESOURCE_LOCATIONS);
    }



    @Override
    public void addArgumentResolvers(List<HandlerMethodArgumentResolver> argumentResolvers) {
        PageableHandlerMethodArgumentResolver resolver = new PageableHandlerMethodArgumentResolver();
        resolver.setPageParameterName("page.page");
        resolver.setSizeParameterName("page.size");
        resolver.setOneIndexedParameters(true);    
        resolver.setMaxPageSize(Integer.parseInt(env.getProperty("pagenation.pagesize")));
        argumentResolvers.add(resolver);
        super.addArgumentResolvers(argumentResolvers);
    }


    @Bean(name = "messageSource")
    public MessageSource messageSource() {
        final ResourceBundleMessageSource messageSource;

        messageSource = new ResourceBundleMessageSource();
        messageSource.setDefaultEncoding("UTF-8");
        messageSource.setBasename("local/messages");

        return messageSource;
    }

    @Bean
    public LocaleChangeInterceptor localeChangeInterceptor() {
        LocaleChangeInterceptor localeChangeInterceptor = new LocaleChangeInterceptor();
        localeChangeInterceptor.setParamName("language");
        return localeChangeInterceptor;
    }

    @Bean(name="localeResolver")
    public SessionLocaleResolver localeResolver() {
        SessionLocaleResolver localeResolver = new SessionLocaleResolver();
        localeResolver.setDefaultLocale(new Locale("en"));
        return localeResolver;
    }

    @Override
    public void addInterceptors(InterceptorRegistry registry) {
        registry.addInterceptor(localeChangeInterceptor());
    }


    @Bean
    WebMvcConfigurerAdapter mvcViewConfigurer() {
        return new WebMvcConfigurerAdapter() {
            @Override
            public void addViewControllers(ViewControllerRegistry registry) {
                registry.addViewController("/login").setViewName("login");
                registry.addViewController("/").setViewName("/login");
            }
        };
    }



}

这是我的 Thymeleaf 配置

@Configuration
public class ThymeleafConfiguration {

    @Bean
    public ITemplateResolver defaultTemplateResolver() {
        final TemplateResolver resolver = new FileTemplateResolver();
        resolver.setSuffix(".html");
        resolver.setPrefix("src/main/resources/templates/");
        resolver.setTemplateMode("HTML5");
        resolver.setCharacterEncoding("UTF-8");
        resolver.setCacheable(false);
        return resolver;
    }

}

所以我确定我不完全理解在 Tomcat 中运行我的 jar 文件“MobileQuestionnaire-0.1.0.jar”和运行我的 war 文件之间的区别。

如果您需要更多信息，请询问，我会提供。

非常感谢。

编辑:

好的，所以我已经设法设置 tomcat 以允许我附加调试器，并且我已经将 Elcipse 连接到它，并且我已经进行了一些挖掘。

How to set up debugger in tomcat

这里失败了:

templateInputStream = resourceResolver.getResourceAsStream(templateProcessingParameters, resourceName);

它试图获取文件

public InputStream getResourceAsStream(final TemplateProcessingParameters templateProcessingParameters, final String resourceName) {
        Validate.notNull(resourceName, "Resource name cannot be null");
        final File resourceFile = new File(resourceName);
        try {
            return new FileInputStream(resourceFile);

这里失败了。路径是:

\src\main\resources\templates\home.html

当我查看 Tomcat 中的 Web 应用程序文件夹时，该文件位于另一个位置:

C:\Program Files\Apache Software Foundation\Tomcat 8.0\webapps\MobileQuestionnaire\WEB-INF\classes\templates\home.html

所以我想我需要更新模板解析器，以便它看起来在正确的位置。有什么建议吗？

好的，所以这个问题只是 Tomcat 无法在 war 文件中找到我的 html/资源。这是我的 gradle 文件:

buildscript {
    repositories {
        mavenCentral()
        maven {
            url "https://plugins.gradle.org/m2/"
        }
    }
    dependencies {
        classpath("org.springframework.boot:spring-boot-gradle-plugin:1.2.5.RELEASE")
        classpath 'com.bmuschko:gradle-cargo-plugin:2.1.1'
        classpath 'mysql:mysql-connector-java:5.1.16'
        classpath 'org.springframework:springloaded:1.2.0.RELEASE'

    }
}


apply plugin: 'java'
apply plugin: 'eclipse'
apply plugin: 'eclipse-wtp'
apply plugin: 'war'
apply plugin: 'idea'
apply plugin: 'spring-boot'
apply plugin: 'com.bmuschko.cargo'


jar {
    baseName = 'MobileQuestionnaire'
    version =  '0.1.0'
}

repositories {
    mavenCentral()
}

sourceCompatibility = 1.8
targetCompatibility = 1.8

dependencies {
    compile("org.springframework.boot:spring-boot-starter-thymeleaf")
    compile("org.springframework.boot:spring-boot-starter-security")

    compile("org.thymeleaf:thymeleaf-spring4")
    compile("nz.net.ultraq.thymeleaf:thymeleaf-layout-dialect")

    testCompile("junit:junit")
}

task wrapper(type: Wrapper) {
    gradleVersion = '2.3'
}

idea {
    module {
        inheritOutputDirs = false
        outputDir = file("$buildDir/classes/main/")
    }
}

这是部署后我的 Web 应用程序目录结构(减去 lib 文件夹):

我想通了。

确保将 CATALINA_HOME 设置为类变量，因为 Tomcat 使用它来确定文件所在的位置。一旦我将 CATALINA_HOME 设置为指向 Tomcat 文件夹中的 bin 目录，一切正常

运行 jar 文件时，使用这个 bean:

/*
     * This is for when we run the jar file
     */
    @Bean
    public ITemplateResolver defaultTemplateResolver() {
        final TemplateResolver resolver = new FileTemplateResolver();
        resolver.setSuffix(".html");
        resolver.setPrefix("src/main/resources/templates/");
        resolver.setTemplateMode("HTML5");
        resolver.setCharacterEncoding("UTF-8");
        resolver.setCacheable(false);
        return resolver;
    }

当我们在 Tomcat 上运行时，使用这个 bean:

/*
     * This is for when we run it on the Tomcat server
     */
    @Bean
    public ServletContextTemplateResolver templateResolver() {
        ServletContextTemplateResolver resolver = new ServletContextTemplateResolver();
        resolver.setPrefix("/src/main/resources/templates/");
        resolver.setSuffix(".html");
        resolver.setTemplateMode("HTML5");
        resolver.setCacheable(false);
        return resolver;

    }

如果两个 beans 都存在，则 jar 将工作。如果两个 bean 都存在，则 war 将无法进行。只有存在第二个 bean 时， war 才会起作用。
