百里香叶片上的百里香失败

Question

使用spring-boot和thymeleaf构建应用程序。在IntelliJ中一切正常，但是当我通过“gradle clean build”构建时，则会出现错误。

这是我的目录结构：

src 
- generated 
- main 
-- java 
-- resources 
--- assets 
---- css/js 
---- templates 
----- *.html 
-- webapp 
- test 
-- groovy 
--- unit & integration tests here 
-- resources 
-- unit 

这是我的gradle文件：

apply plugin: 'java' 
apply plugin: 'groovy' 
apply plugin: 'idea' 
apply plugin: 'spring-boot' 
apply plugin: 'jacoco' 
apply plugin: 'war' 
apply plugin: 'maven' 

def generatedResources = "$buildDir/generated-resources/main" 

configurations { 
    querydslapt 
} 

buildscript { 
    repositories { 
     maven { url "http://repo.spring.io/libs-snapshot" } 
     mavenLocal() 
    } 
    dependencies { 
     classpath("org.springframework.boot:spring-boot-gradle-plugin:1.0.0.RC4") 
    } 
} 


repositories { 
    mavenCentral() 
    maven {url "http://repo.spring.io/libs-snapshot"} 
    maven {url 'http://repo.spring.io/milestone' } 
} 

dependencies {

    testCompile("junit:junit") 
} 

jacocoTestReport { 
    group = "Reporting" 
    description = "Generate Jacoco coverage reports after running tests." 
} 

sourceSets { 

    generated { 
     java { 
      srcDirs = ['src/main/generated'] 
     } 
    } 
    main { 
     //let's register an output folder on the main SourceSet: 
    output.dir(generated, builtBy: 'generateQueryDSL') 
     java { 
      srcDirs = [] 
     } 
     groovy { 
      srcDirs = ['src/main/groovy', 'src/main/java'] 
     } 
     resources { 
      srcDirs = ['src/main/resources'] 
     } 

     output.resourcesDir = "build/classes/main" 
    } 

    test { 
     java { 
      srcDirs = [] 
     } 
     groovy { 
      srcDirs = ['src/test/groovy', 'src/test/java'] 
     } 
     resources { 
      srcDirs = ['src/test/resources'] 
     } 

     output.resourcesDir = "build/classes/test" 
    } 
} 


task generateQueryDSL(type: JavaCompile, group: 'build', description: 'Generates the QueryDSL query types') { 
    source = sourceSets.main.java 
    classpath = configurations.compile + configurations.querydslapt 
    options.compilerArgs = [ 
      "-proc:only", 
      "-processor", "com.mysema.query.apt.jpa.JPAAnnotationProcessor" 
    ] 
    destinationDir = sourceSets.generated.java.srcDirs.iterator().next() 
} 

compileJava { 
    dependsOn generateQueryDSL 
    source generateQueryDSL.destinationDir 
} 

compileGeneratedJava { 
    dependsOn generateQueryDSL 
    options.warnings = false 
    classpath += sourceSets.main.runtimeClasspath 
} 

clean { 
    delete sourceSets.generated.java.srcDirs 
} 

idea { 
    module { 
     sourceDirs += file('src/main/generated') 
    } 
} 

task wrapper(type: Wrapper) { 
    gradleVersion = '1.11' 
} 

我有UI配置为这样：

@Configuration 
public class MvcConfig extends WebMvcConfigurerAdapter { 
... 
    @Override 
    public void addViewControllers(ViewControllerRegistry registry) { 
     registry.addViewController("/home").setViewName("index"); 
    ... 
    } 

// removed to try and find the css/js/images 
//@Override 
//public void addResourceHandlers(ResourceHandlerRegistry registry) { 
// registry.addResourceHandler("/resources/**").addResourceLocations("/resources/"); 
//}  

... 
} 

下面是一个例子测试：

@SpringApplicationConfiguration 
class TreasuryStatusEvaluatorTest extends Specification { 

    @Shared 
    def ConfigurableApplicationContext context 

    @Shared 
    private StatusRepository statusRepository 

    void setupSpec() { 
     Future future = Executors.newSingleThreadExecutor().submit(
       new Callable() { 
        @Override 
        public ConfigurableApplicationContext call() throws Exception { 
         return (ConfigurableApplicationContext) SpringApplication.run(OFAC.class) 
        } 
       }) 
     context = future.get(60, TimeUnit.SECONDS) 
     treasuryStatusEvaluator = context.getBean(TreasuryStatusEvaluator.class) 
     statusRepository = context.getBean(StatusRepository.class) 
    } 

    void cleanupSpec() { 
     if (context != null) { 
      context.close() 
     } 
    } 
... 
}

这些测试。但是，当我运行命令行的测试中，我得到的错误，如：

Caused by: java.lang.IllegalStateException: Cannot find template location: class path resource [templates/] (please add some templates or check your Thymeleaf configuration) 

我看到，在春季启动有与thymeleaf目录结构的问题：https://github.com/spring-projects/spring-boot/issues/424和它似乎是一个模板目录是必须的。我没有使用任何模板，只是HTML。

更新＃1： 我感动的HTML下的src /主/资源/ *

更新＃2： 我感动的CSS/JS /库为src /主/资源/静 我试过把它们放在src/main/static下，但是那也行不通

Answer 1

现在有一个1.0.1.RELEASE的Spring Boot，所以你应该使用它（它可能只是解决你的问题） 。不过，通常情况下，只要将模板放入“classpath：/ templates”（这些html文件是Thymeleaf所称的“模板”），我不会期望您需要Thymeleaf配置。如果您想将它们放在其他地方，请使用spring.thymeleaf.prefix指定模板位置（请参阅docs here）。

如果您希望自己完全配置Thmyeleaf，那么您需要使用模板解析器（“defaultTemplateResolver”）的常规bean名称，以便Boot知道您在做什么。详细信息在ThymeleafAutoConfiguration - 文档中明确提出了一些功能，但似乎并非如此。

Answer 2

如果你得到同样的异常

Caused by: java.lang.IllegalStateException: Cannot find template location: class path resource [templates/] (please add some templates or check your Thymeleaf configuration) 

但使用SpringBoot 1.2.0-RELEASE，它可能是简单的，你需要创建一个目录的src /主/资源/模板。

我从SpringBoot 1.1.9升级到1.2.0并开始得到这个异常。添加目录修复它。

Answer 3

或者，如果您收到此例外情况并且不想使用thymeleaf，则可以通过使用...

配置/ application.yml

spring.groovy.template.check-template-location: false 

更多春天的最新版本，实际上会告诉你这堆栈跟踪...

即

Caused by: java.lang.IllegalStateException: Cannot find template location: classpath:/templates/ (please add some templates, check your Groovy configuration, or set spring.groovy.template.check-template-location=false)
