Spring boot gradle cannot load sqlserver dependency

Question

I am trying to build a springboot application, with microsoft sql server connection. I build connection to mysql and it worked fine, but now i cannot connect to my mssql database, because springboot gradle script doesn't load the 'com.microsoft.sqlserver:sqljdbc4' jar. I tried to load the jar via gradle script in a non-springboot project and it worked fine. Is springboot doing something i don't know? Or is there another problem?

My gradle-script:

buildscript {
    ext {
        springBootVersion = '1.4.0.RELEASE'
    }
    repositories {
        mavenCentral()
    }
    dependencies {
        classpath("org.springframework.boot:spring-boot-gradle-plugin:${springBootVersion}")
    }
}

apply plugin: 'java'
apply plugin: 'eclipse'
apply plugin: 'spring-boot'

jar {
    baseName = 'BEAT-Surflet'
    version = '0.0.1-SNAPSHOT'
}
sourceCompatibility = 1.8
targetCompatibility = 1.8

repositories {
    mavenCentral()
}


dependencies {
    compile('org.springframework.boot:spring-boot-starter-thymeleaf')
    compile('com.microsoft.sqlserver:sqljdbc4')
    compile('org.springframework.boot:spring-boot-starter-web')
    compile('org.springframework:spring-jms')
    compile('org.apache.activemq:activemq-broker')  
    testCompile('org.springframework.boot:spring-boot-starter-test')
}

Maybe the problem is, that springboot tries to load the version by himself or conflicting because of it. I tried to exlicit give him the version too ( 'com.microsoft.sqlserver:sqljdbc4:4.0' ), but it didn't work either. So why my gradle-script or my springboot project doesn't load the mssql jar?

Answer 1

I had simmilar issues. I Solved this by using net.sourceforge.jtds 1.3.1. driver. I suggest using this driver for MSSQL databases. Microsoft driver is really bugged and it do not support of some widely used data types.

Answer 2

I'm guessing you really want Spring Boot, not Gradle, to be able to use MS SQL Server -- Gradle just puts the dependency on the classpath.

You may need to specify spring.datasource.driver-class-name in you application properties/yml file. See the Working with SQL Databases section of the documentation.

Good luck.
