Spring Boot DB Migration with Flyway to MySQL - mysql

Question

I have a Gradle Spring Boot web application that migrates from H2 to PostgreSQL using Flyway. I am trying to convert this to migrate from H2 to MySQL. The build.gradle file is:
buildscript {
ext {
springBootVersion = '1.3.0.RELEASE'
}
repositories {
maven { url "http://repo.spring.io/milestone" }
mavenCentral()
}
dependencies {
classpath("org.springframework.boot:spring-boot-gradle-plugin:${springBootVersion}")
}
}
apply plugin: 'java'
apply plugin: 'eclipse'
apply plugin: 'idea'
apply plugin: 'spring-boot'
apply plugin: 'war'
war {
baseName = 'demo'
version = '0.0.1-SNAPSHOT'
archiveName = 'demo.war'
}
sourceCompatibility = 1.8
targetCompatibility = 1.8
repositories {
maven { url "http://repo.spring.io/milestone" }
mavenCentral()
}
dependencies {
compile("org.springframework.boot:spring-boot-starter-actuator")
compile("org.springframework.boot:spring-boot-starter-web")
compile("org.springframework.boot:spring-boot-starter-data-jpa")
compile("org.springframework.boot:spring-boot-starter-thymeleaf")
compile("org.springframework.boot:spring-boot-starter-security")
compile("com.h2database:h2")
compile("org.postgresql:postgresql:9.4-1201-jdbc41")
compile("org.flywaydb:flyway-core")
testCompile("org.springframework.boot:spring-boot-starter-test")
}
eclipse {
classpath {
containers.remove('org.eclipse.jdt.launching.JRE_CONTAINER')
containers 'org.eclipse.jdt.launching.JRE_CONTAINER/org.eclipse.jdt.internal.debug.ui.launcher.StandardVMType/JavaSE-1.7'
}
}
task wrapper(type: Wrapper) {
gradleVersion = '1.12'
}
There is an application.yml file:
error:
whitelabel:
enabled: false
amazon:
associate_id: habuma-20
spring:
jpa:
hibernate:
ddl-auto: none
---
spring:
profiles: production
datasource:
url: jdbc:postgresql://localhost:5432/readinglist
username: habuma
password:
jpa:
database-platform: org.hibernate.dialect.PostgreSQLDialect
In build.gradle, I replaced
compile("org.postgresql:postgresql:9.4-1201-jdbc41")
with
compile("mysql:mysql-connector-java:5.1.5")
and changed application.yml to
error:
whitelabel:
enabled: false
amazon:
associate_id: habuma-20
spring:
jpa:
hibernate:
ddl-auto: none
---
spring:
profiles: production
datasource:
url: jdbc:mysql://localhost:3306/readinglist
username: root
password: ******
jpa:
database-platform: org.hibernate.dialect.MySQL5Dialect
To get the "production" profile I set an environment variable SPRING_PROFILES_ACTIVE=production. Then run with the command java -jar build/libs/demo.war. When the application tries to boot up I get the following error:
org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'org.springframework.security.config.annotation.web.configuration.WebSecurityConfiguration': Injection of autowired dependencies failed;

I'm not sure what the solution to this Checksum mismatch is.
