无法使用Gradle和Spring Boot加载驱动程序类：com.mysql.jdbc.Driver

我的问题如下.我正在学习如何使用JDBC,Gradle和Spring框架(我对这些主题不熟悉).我一直试图实现以下example与一个区别,MysqL数据库而不是POSTGResql.

就像我在标题中指定的那样,我的应用程序以以下错误结束无法加载驱动程序类：com.MysqL.jdbc.Driver(帖子末尾的堆栈跟踪).

当然我在发布这个问题之前一直在谷歌搜索和阅读,我发现com.MysqL.jdbc.Driver应该在程序中使用loader加载,或者也可以使用Gradle构建脚本来完成.

我的问题如下：

>为什么作者示例在没有加载器的情况下工作(在构建脚本中的程序中)
>如果加载器是绝对必要的,你能简要解释一下如何实现它吗？

我修改的build.gradle文件：

buildscript { 
    repositories { 
        maven { url "http://repo.spring.io/libs-snapshot" } 
    } 
    dependencies { 
        classpath("org.springframework.boot:spring-boot-gradle-plugin:0.5.0.M6") 
        classpath 'MysqL:mysql-connector-java:5.1.34'  
    } 
} 

apply plugin: "java" 
apply plugin: "spring-boot" 

buildDir = "out" 

jar { 
    basename = "sb-jdbc" 
    version = "0.1" 
} 

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

dependencies { 
    def springBootVersion = '1.0.0.RC1'
    compile("org.springframework.boot:spring-boot-starter-jdbc:$springBootVersion")
    compile("org.springframework.boot:spring-boot-starter-web:$springBootVersion")
    compile("org.springframework.boot:spring-boot-starter-data-jpa:$springBootVersion")
    compile("MysqL:mysql-connector-java:5.1.34")

    TESTCompile("org.springframework.boot:spring-boot-starter-test:$springBootVersion")
    TESTCompile("junit:junit:4.11")
} 

我的application.properties文件：

spring.datasource.driverClassName=com.MysqL.jdbc.Driver
spring.datasource.url=jdbc:MysqL://localhost/:3306/******
spring.datasource.username=root
spring.datasource.password=******

# Specify the DBMS
spring.jpa.database = MysqL

# Show or not log for each sql query
spring.jpa.show-sql = true

# Hibernate setTings are prefixed with spring.jpa.hibernate.*
spring.jpa.hibernate.ddl-auto = update
spring.jpa.hibernate.dialect = org.hibernate.dialect.MysqL5Dialect
spring.jpa.hibernate.naming_strategy = org.hibernate.cfg.ImprovedNamingStrategy

编辑#1

正如Kamoor先生所说,这可能是缺少本地* jar文件的问题.我怀疑Gradle会自动从存储库下载它,万一我不会手动添加它(我在STS上工作).在这里我们可以看到mysql-connector-java jar就在那里.

我很抱歉这些屏幕拍摄,我只是不知道其他方式来表明我添加它(我不习惯EclipsE).
