Question

我正在开发一个Spring / hibernate项目，但我无法使其工作。通常，Spring DI工作正常。我的控制器获取注入的服务类，服务类获取注入的DAO类。但是，只要我将spring-orm依赖项添加到pom文件中，我就会得到 NoClassDefFoundError：NoUniqueBeanDefinitionException。这是堆栈跟踪：

Answer 1

如果将spring-orm添加到pom时出现问题。也许你与版本有冲突。尝试以这种方式添加exclusion到spring-orm：

    <dependency>
            <groupId>org.springframework</groupId>
            <artifactId>spring-jdbc</artifactId>
            <version>${org.springframework-version}</version>
            <exclusions>
                <exclusion>
                    <artifactId>spring-beans</artifactId>
                    <groupId>org.springframework</groupId>
                </exclusion>                    
            </exclusions>
    </dependency>

Answer 2

找到它：问题是jersey-spring依赖项导致Maven下载错误版本（3.0.0）的一些弹簧库。我不得不手动排除库以使其工作：

<dependency>
        <groupId>com.sun.jersey.contribs</groupId>
        <artifactId>jersey-spring</artifactId>
        <version>1.19.1</version>
        <exclusions>
            <exclusion>
                <groupId>org.springframework</groupId>
                <artifactId>spring</artifactId>
            </exclusion>
            <exclusion>
                <groupId>org.springframework</groupId>
                <artifactId>spring-core</artifactId>
            </exclusion>
            <exclusion>
                <groupId>org.springframework</groupId>
                <artifactId>spring-web</artifactId>
            </exclusion>
            <exclusion>
                <groupId>org.springframework</groupId>
                <artifactId>spring-beans</artifactId>
            </exclusion>
            <exclusion>
                <groupId>org.springframework</groupId>
                <artifactId>spring-context</artifactId>
            </exclusion>
            <exclusion>
                <groupId>org.springframework</groupId>
                <artifactId>spring-aop</artifactId>
            </exclusion>            
        </exclusions>
    </dependency>
