如何从弹簧引导中排除依赖关系 [英] how to exclude dependencies from spring boot

问题描述

我使用spring引导，以下是我的gradle文件

  buildscript {
 ext {
 springBootVersion ='2.0.0.BUILD-SNAPSHOT'
} 
知识库{
 mavenCentral（）
 maven {urlhttps://repo.spring.io/snapshot} 
 maven {urlhttps://repo.spring.io/milestone} 
} 
依赖关系{
 classpath（org.springframework.boot：spring-boot-gradle -plugin：$ {springBootVersion}）
} 
} 
 
 apply plugin：'java'
 apply plugin：'eclipse-wtp'
 apply插件：'org.springframework.boot'
 apply插件：'io.spring.dependency-management'
 apply插件：'war'
 
 version ='0.0.1- SNAPSHOT'
 sourceCompatibility = 1.8 
 
存储库{
 mavenCentral（）
 maven {urlhttps://repo.spring.io/snapshot} 
 maven {urlhttps://repo.spring.io/milestone} 
} 
 
配置{
 providesRuntime 
 
 
 dependencies {
 compile（'org.springframework.boot：spring-boot-starter-data-jpa：1.2.1.RELEASE'）
'compile（'org.springframework.boot：spring-boot-starter-web'）
 compile（com.h2database：h2）
 providedRuntime（'org.springframework.boot：spring-boot- starter-tomcat'）
 testCompile（'org.springframework.boot：spring-boot-starter-test'）
} 
  

while m在gradle文件中添加以下依赖项：

  org.springframework.boot： spring-boot-starter-data-jpa：1.2.1.RELEASE 
  

其中包括其他一些依赖关系像hibernate n所有我现在不需要它（只想使用spring数据jpa）导致许多其他问题
所以我怎么能只使用spring-data-jpa及其相关的依赖项？

尝试禁用，例如exclude = {HibernateJpaAutoConfiguration.class}，但不会很好

提前提示

解决方案

我猜的最简单的解决方案就是包含 spring-data-jpa ，而不是 spring-boot-starter-data-jpa ：

  compile（'org.springframework.data:spring-data-jpa:2.0.0.M2'）
  

或者，如果您真的想离开启动器，可能会尝试执行以下操作：

<$ p $编译（'org.springframework.boot：spring-boot-starter-data-jpa'）{
exclude（module：'hibernate-core'）
exclude（module ：'hibernate-entitymanager'）
}

但明白这一点， code> spring-data-jpa 你必须有一个像 hibernate 这样的持久化提供者，只是因为 spring- data-jpa 本身不过是 JPA 之上的抽象，而也是持久提供者的抽象，比如 hiberna te 或 eclipselink 。

更新

如果您想要将所有jpa依赖关系保留在gradle构建脚本中，但不希望 spring-boot 将它们用于有一阵子，你必须禁用 DataSourceAutoConfiguration 和 HibernateJpaAutoConfiguration 。

  @SpringBootApplication（exclude = {DataSourceAutoConfiguration.class，HibernateJpaAutoConfiguration.class}）
  

I am using spring boot and following is my gradle file

    buildscript {
    ext {
        springBootVersion = '2.0.0.BUILD-SNAPSHOT'
    }
    repositories {
        mavenCentral()
        maven { url "https://repo.spring.io/snapshot" }
        maven { url "https://repo.spring.io/milestone" }
    }
    dependencies {
        classpath("org.springframework.boot:spring-boot-gradle-plugin:${springBootVersion}")
    }
}

apply plugin: 'java'
apply plugin: 'eclipse-wtp'
apply plugin: 'org.springframework.boot'
apply plugin: 'io.spring.dependency-management'
apply plugin: 'war'

version = '0.0.1-SNAPSHOT'
sourceCompatibility = 1.8

repositories {
    mavenCentral()
    maven { url "https://repo.spring.io/snapshot" }
    maven { url "https://repo.spring.io/milestone" }
}

configurations {
    providedRuntime
}

dependencies {
    compile('org.springframework.boot:spring-boot-starter-data-jpa:1.2.1.RELEASE')
    compile('org.springframework.boot:spring-boot-starter-web')
    compile("com.h2database:h2")
    providedRuntime('org.springframework.boot:spring-boot-starter-tomcat')
    testCompile('org.springframework.boot:spring-boot-starter-test')
}

while m adding in gradle file the following dependecy

org.springframework.boot:spring-boot-starter-data-jpa:1.2.1.RELEASE

its including bunch of other dependencies like hibernate n all that i don't need it for now(just wanted to use spring data jpa) which cause many other problem so how can i use only spring-data-jpa and its related dependency only ?

tried to disable like exclude = { HibernateJpaAutoConfiguration.class} but does't go well

Thnks in advance

解决方案

The simplest solution I guess would be just to include spring-data-jpa, not spring-boot-starter-data-jpa:

compile('org.springframework.data:spring-data-jpa:2.0.0.M2')

Or if you're really want to left starter, than you might try to do something like:

compile('org.springframework.boot:spring-boot-starter-data-jpa') {
    exclude(module: 'hibernate-core')
    exclude(module: 'hibernate-entitymanager')
}

But understand this, in order to use spring-data-jpa you have to have a persistent provider like hibernate, just because spring-data-jpa itself is nothing more than an abstraction on top of JPA which in turn is an abstraction as well on top of persistent providers like hibernate or eclipselink.

Update

If you want to leave all jpa dependencies in gradle build script, but don't want spring-boot to use them for a while, then you have to disable both DataSourceAutoConfiguration and HibernateJpaAutoConfiguration as well.

@SpringBootApplication(exclude = {DataSourceAutoConfiguration.class, HibernateJpaAutoConfiguration.class})
