我使用Spring Boot 1.0.2.RELEASE成功开发了一个原型(直到今天为1.0.1.RELEASE)。
我搜索并搜索过以下解决方案: Spring Boot jdbc datasource autoconfiguration fails on standalone tomcat Spring Boot / Spring Data import.sql doesn't run Spring-Boot-1.0.0.RC1
他们都建议让Spring Boot完成这项工作。 当使用H2时,一切正常,但当我尝试切换到PostgreSQL时,我得到:
Caused by: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'entityManagerFactory' defined in class path resource [org/springframework/boot/autoconfigure/orm/jpa/HibernateJpaAutoConfiguration.class]: Instantiation of bean failed; nested exception is org.springframework.beans.factory.BeanDefinitionStoreException: Factory method [public org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean org.springframework.boot.autoconfigure.orm.jpa.JpaBaseConfiguration.entityManagerFactory(org.springframework.orm.jpa.JpaVendorAdapter)] threw exception; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type [javax.sql.DataSource] is defined
我的build.gradle如下:
loadConfiguration()
def loadConfiguration() {
def environment = hasProperty('env') ? env : 'dev'
project.ext.envrionment = environment
println "Environment is set to $environment"
def configFile = file('config.groovy')
def config = new ConfigSlurper("$environment").parse(configFile.toURL())
project.ext.config = config
}
buildscript {
ext {
springBootVersion = '1.0.2.RELEASE'
}
repositories {
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'
apply plugin: 'groovy'
war {
baseName = 'test'
version = '0.0.1-SNAPSHOT'
}

repositories {

compile("org.springframework.boot:spring-boot-starter-web:${springBootVersion}")

//compile("com.h2database:h2")
testCompile("org.springframework.boot:spring-boot-starter-test:${springBootVersion}")
}
task wrapper(type: Wrapper) {
gradleVersion = '1.11'
}
application.properties:
spring.jpa.database=POSTGRESQL
spring.jpa.show-sql=false
spring.jpa.hibernate.ddl-auto=update
spring.database.driverClassName=org.postgresql.Driver
spring.datasource.url=jdbc:postgresql://localhost/cms
spring.datasource.username=cms
spring.datasource.password=NA
删除application.properties并将依赖关系更改回H2,一切正常。
我无法找到我做错的地方: - (

这是从哪里来的:database.driverClassName=org.postgresql.Driver
?你的意思是spring.datasource.driverClassName
吗?

如果没有刷新依赖项,请尝试重新导入mvn项目,并在pom.xml中添加以下内容
<dependency>
<groupId>postgresql</groupId>
<artifactId>postgresql</artifactId>
<version>9.1-901.jdbc4</version>
</dependency>

我的build.gradle
中有这个:
实现'org.postgresql:postgresql:版本号'
但是,无论我做什么,该罐子都从未下载过。
作为一种解决方法,我从here(单击Jar(...)
)下载了jar,然后将其手动添加到了 Java Build Path-Libraries 中。
不理想,但这是2分钟内唯一起作用的东西!
答案 3 :(得分:0)
spring.datasource.driver-class-name=org.postgresql.Driver
如果您最近刚刚将 postgres 添加到您的依赖项,请确保重新加载您的项目。
