C3p0 with Hibernate 4.2 error: setCharacterStream(ILjava/io/Reader;J)V is abstract

Question

我将 Hibernate 4.2 与 c3p0 一起使用，但出现此错误：Method com/mchange/v2/c3p0/impl/NewProxyPreparedStatement.setCharacterStream(ILjava/io/Reader;J)V is abstract

有人知道我应该使用哪个版本吗？这是我当前的 Maven 依赖项列表：

<dependency>
    <groupId>com.mchange</groupId>
    <artifactId>c3p0</artifactId>
    <version>0.9.2</version>
</dependency>

<dependency>
    <groupId>org.hibernate</groupId>
    <artifactId>hibernate-c3p0</artifactId>
    <version>4.2.0.Final</version>
</dependency>

Answer 1

PreparedStatement.setCharacterStream() method was added to JDBC 4 and according to C3P0 release notes:

As of version 0.9.5, c3p0 fully supports the jdbc4 spec.

所以你需要update the C3p0 library to 0.9.5:

<dependency>
    <groupId>com.mchange</groupId>
    <artifactId>c3p0</artifactId>
    <version>0.9.5</version>
</dependency>

您还可以从 Hibernate 中排除 C3P0 依赖项，以确保 Maven 使用您明确配置的依赖项：

<dependency>
    <groupId>org.hibernate</groupId>
    <artifactId>hibernate-c3p0</artifactId>
    <version>4.2.0.Final</version>
    <exclusions>
        <exclusion>
            <artifactId>c3p0</artifactId>
            <groupId>c3p0</groupId>
        </exclusion>
    </exclusions>
</dependency>

Answer 2

使用artifactId c3p0 0.9.5.2就可以了！

<dependency>
    <groupId>com.mchange</groupId>
    <artifactId>c3p0</artifactId>
    <version>0.9.5.2</version>
</dependency>

Answer 3

在迁移到休眠 4 之后我不得不添加 c3p0-0.9.5.jar 和 mchange-commons-java-0.2.15.jar（jar , 因为它不是 maven 项目)
