【中文标题】使用 spring-data-jpa 和完整的 tomcat-jdbc 配置的 spring boot 为 ResetAbandonedTimer 抛出 java.lang.ClassNotFoundException

【英文标题】：spring boot with spring-data-jpa and full tomcat-jdbc config throws java.lang.ClassNotFoundException for ResetAbandonedTimer

【问题描述】：

我正在使用带有以下 pom 依赖项的 spring boot 1.3.0.RELEASE

<dependencies>
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-data-jpa</artifactId>
    </dependency>
    <dependency>
        <groupId>org.springframework.boot</groupId>

        <artifactId>spring-boot-starter-thymeleaf</artifactId>
    </dependency>
    <dependency>

    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-test</artifactId>
        <scope>test</scope>
    </dependency>
</dependencies>

我正在尝试让 JPA 正常工作，并且在我的 application.properties 中使用以下内容一切正常

# Connection url for the database
spring.datasource.url = jdbc:oracle:thin:@**********
# Username and password
spring.datasource.username = **********
spring.datasource.password = *********

当我为 tomcat-jdbc 切换到完整的 dbcp 配置时，如下所示：

spring.datasource.driver-class-name=oracle.jdbc.OracleDriver
spring.datasource.url=jdbc:oracle:thin:@**********
spring.datasource.username=*****
spring.datasource.password=*****
spring.datasource.initial-size=0
spring.datasource.max-active=10
spring.datasource.default-auto-commit=true
spring.datasource.default-transaction-isolation=2
spring.datasource.fair-queue=false
spring.datasource.jdbc-interceptors=ConnectionState;StatementFinalizer;ResetAbandonedTimer"
spring.datasource.jmx-enabled=true
spring.datasource.log-abandoned=true
spring.datasource.max-idle=1
spring.datasource.max-wait=30000
spring.datasource.min-evictable-idle-time-millis=60000
spring.datasource.min-idle=1
spring.datasource.remove-abandoned=true
spring.datasource.remove-abandoned-timeout=300
spring.datasource.test-on-borrow=true
spring.datasource.test-on-return=false
spring.datasource.test-while-idle=false
spring.datasource.time-between-eviction-runs-millis=10000
spring.datasource.use-equals=false
spring.datasource.validation-interval=60000
spring.datasource.validation-query=SELECT 2+2 FROM DUAL

我得到以下堆栈跟踪

即使使用不同的 spring boot 版本似乎也是如此.... 我的配置（取自我们已经正常使用的 spring 数据源 bean）不是启动所期望的吗？

干杯

【参考方案1】：

错字。

从最后的spring.datasource.jdbc-interceptors=ConnectionState;StatementFinalizer;ResetAbandonedTimer" 中删除"。

我很感激你！逆天！经过这么多年的发展，您会认为被拼写错误咬伤的日子已经一去不复返了……非常感谢！很抱歉浪费了字节！

我很高兴为您提供帮助 ;)
