為SQL Server創建DataSource的Spring錯誤

[英]Spring error creating DataSource for SQL Server

 原文  2017-04-17 20:42:23  4   1    java/ spring/ spring-mvc/ jdbc

問題描述

我正在使用DataAccess（使用Spring）構建WebApi。 我有一個bean來創建這樣的數據源： 

@Bean
public DataSource getDataSource() {
    DriverManagerDataSource dataSource = new DriverManagerDataSource();
    dataSource.setDriverClassName("com.microsoft.sqlserver.jdbc.SQLServerDriver");
    dataSource.setUrl("jdbc:sqlserver://localhost/DawDB");
    dataSource.setUsername("root");
    dataSource.setPassword("P@ssw0rd");

    return dataSource;
}

但每次我嘗試運行App我得到： 

Could not load JDBC driver class
[com.microsoft.sqlserver.jdbc.SQLServerDriver]

我已經嘗試添加jar文件throw gradle並手動添加為外部庫。

我錯過了什么嗎？

編輯：

在Gradle上我添加了依賴項： 

compile('com.microsoft.sqlserver:sqljdbc4:4.0')

EDIT2：

正如我解釋的那樣，我已經嘗試將jar文件添加到我的外部庫中。

啟動ApplicationContext時出錯。 要顯示自動配置報告，請在啟用“debug”的情況下重新運行應用程序。

完全gradle： 

buildscript {
    ext {
        springBootVersion = '1.5.2.RELEASE'
    }
    repositories {
        mavenCentral()
    }
    dependencies {
        classpath("org.springframework.boot:spring-boot-gradle-plugin:${springBootVersion}")
    }
}

apply plugin: 'java'
apply plugin: 'eclipse'
apply plugin: 'org.springframework.boot'

version = '0.0.1-SNAPSHOT'
sourceCompatibility = 1.8

repositories {
    mavenCentral()
}


dependencies {
    compile('org.springframework:spring-web:4.3.7.RELEASE')
    compile('org.springframework.boot:spring-boot-starter-web')
    compile('io.springfox:springfox-swagger2:2.4.0')
    compile('io.springfox:springfox-swagger-ui:2.4.0')
    compile('com.microsoft.sqlserver:sqljdbc4:4.0')

有同樣的問題，但對我來說工作添加了com.microsoft.sqlserver:mssql-jdbc依賴。
您正在使用的Java版本。
他們每個人都有聯合： 7.4.1.jre8
