Question

我正在做我的第一个maven spring Rest项目，其中包括一个嵌入式tomcat服务和一些MongoDb查询。我对Maven和Spring都很陌生，似乎无法理解这个错误。

Exception in thread "main" java.lang.IllegalAccessError: tried to access method org.springframework.core.io.support.SpringFactoriesLoader.loadFactoryNames(Ljava/lang/Class;Ljava/lang/ClassLoader;)Ljava/util/List; from class org.springframework.boot.SpringApplication
    at org.springframework.boot.SpringApplication.getSpringFactoriesInstances(SpringApplication.java:260)
    at org.springframework.boot.SpringApplication.initialize(SpringApplication.java:226)
    at org.springframework.boot.SpringApplication.<init>(SpringApplication.java:200)
    at org.springframework.boot.SpringApplication.run(SpringApplication.java:920)
    at org.springframework.boot.SpringApplication.run(SpringApplication.java:909)
    at com.cave.spring.firstSpring.Application.main(Application.java:12)

这是我得到的例外。我正在尝试启动嵌入式tomcat服务，但我一直在收到错误。我认为我的pom.xml中有一些不兼容的东西：

Answer 1

尝试删除<version>属性，以获取spring boot父pom中定义的依赖项（就像您对spring-boot-starter-web所做的那样）。

 <dependencies>
    <dependency>
        <groupId>org.springframework</groupId>
        <artifactId>spring-core</artifactId>
    </dependency>
    <dependency>
        <groupId>org.springframework</groupId>
        <artifactId>spring-beans</artifactId>
    </dependency>
    <dependency>
        <groupId>org.springframework</groupId>
        <artifactId>spring-context</artifactId>
    </dependency>

    <dependency>
        <groupId>org.mongodb</groupId>
        <artifactId>mongo-java-driver</artifactId>
        <version>2.11.0</version>
        <!-- i dont know if this is defined in the parent pom -->
    </dependency>

    <dependency>
        <groupId>org.springframework.data</groupId>
        <artifactId>spring-data-mongodb</artifactId>
        <version>1.3.3.RELEASE</version>
        <!-- i dont know if this is defined in the parent pom -->
    </dependency>
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-web</artifactId>
    </dependency>
    <dependency>
        <groupId>com.fasterxml.jackson.core</groupId>
        <artifactId>jackson-databind</artifactId>
    </dependency>

    <dependency> 
      <groupId>org.springframework</groupId> 
      <artifactId>spring-aspects</artifactId>          
    </dependency>
</dependencies>

Answer 2

我最终设法解决了这个问题。我认为存在一些依赖性问题。我剥离了pom并重新导入了依赖项
