使用Spring Boot进行Spring Data Rest和spring-data-rest-hal-browser集成

问题

Spring Data REST Reference Documentation说

dependencies {
    compile 'org.springframework.data:spring-data-rest-hal-browser'
}

足以在使用Spring Boot的同时将HAL浏览器与Spring Data Rest集成，但Gradle抱怨除非我指定特定版本，否则无法找到此依赖项，因此我通过指定the latest one available in central repository修复了它（没有其他版本可用库）。指定版本后，依赖项已解析，但在Spring Boot容器初始化期间出现错误：

但是，如果删除spring-data-rest-hal-browser:2.4.0.RELEASE依赖项，我的应用程序会成功初始化并按预期工作。

问题

如何正确设置build.gradle以使我的应用程序与HAL浏览器正确集成？

build.gradle 

buildscript {
    ext {
        springBootVersion = '1.2.7.RELEASE'
    }

    repositories {
        mavenCentral()
    }
}

dependencies {
    classpath("org.springframework.boot:spring-boot-gradle-plugin:${springBootVersion}")
    classpath('io.spring.gradle:dependency-management-plugin:0.5.2.RELEASE')
}

[...]

repositories {
    mavenCentral()
    flatDir {
       dirs 'lib'
    }
}

dependencies {
    compile('org.springframework.boot:spring-boot-starter-actuator')
    compile('org.springframework.boot:spring-boot-starter-data-jpa')
    compile('org.springframework.boot:spring-boot-starter-data-rest')
    compile('org.springframework.boot:spring-boot-starter-remote-shell')
    compile('org.springframework.data:spring-data-rest-hal-browser:2.4.0.RELEASE')
    compile('org.projectlombok:lombok:1.16.6')
    compile name: 'ojdbc6'
    testCompile('org.springframework.boot:spring-boot-starter-test')
    testCompile('org.springframework.restdocs:spring-restdocs-mockmvc:1.0.0.RELEASE')
}

HAL浏览器的自动版本管理仅适用于处于候选发布阶段的Spring Boot 1.3.0，应该很快就会发布。发布候选版本对我来说非常稳定，所以你可以考虑通过将你的版本更新到1.3.0.RC1来试一试，我希望能解决这个问题，如下所示：

buildscript {
    ext {
        springBootVersion = '1.3.0.RC1'
    }
    repositories {
        mavenCentral()
        maven { url 'https://repo.spring.io/milestone/' }
    }
    dependencies {
        classpath("org.springframework.boot:spring-boot-gradle-plugin:${springBootVersion}")
        classpath "io.spring.gradle:dependency-management-plugin:0.5.2.RELEASE"
    }
}

repositories {
    mavenCentral()
    flatDir {
       dirs 'lib'
    }
}

dependencies {
    compile('org.springframework.boot:spring-boot-starter-actuator')
    compile('org.springframework.boot:spring-boot-starter-data-jpa')
    compile('org.springframework.boot:spring-boot-starter-data-rest')
    compile('org.springframework.boot:spring-boot-starter-remote-shell')
    compile('org.springframework.data:spring-data-rest-hal-browser')
    compile('org.projectlombok:lombok:1.16.6')
    compile name: 'ojdbc6'
    testCompile('org.springframework.boot:spring-boot-starter-test')
    testCompile('org.springframework.restdocs:spring-restdocs-mockmvc')
}

您可以在此处查看1.3.0.RC1的托管依赖关系版本：

http://docs.spring.io/spring-boot/docs/1.3.0.RC1/reference/htmlsingle/#appendix-dependency-versions

如果您查看1.2.7的托管依赖关系版本，spring-data-rest-hal-browser和spring-restdocs-mockmvc都不存在，您会注意到。
