创建名称为 'accountController' 的 bean 时出错
Error creating bean with name 'accountController'
因此，我们终于设法将我们的 Spring 框架从版本 3.2 更新到 4.2.25。经过一些痛苦的过程后，我现在陷入了这个异常：Error creating bean with name 'accountController': Injection of resource dependencies failed; nested exception is org.springframework.beans.factory.BeanCreationException。

不确定是否相关：我正在使用 javax.servlet-api-3.1。
现在AccountService.java:
@Service("accountService")
@Transactional
public class AccountService
{
protected static Logger log = LogManager.getLogger(AccountService.class);
private NamedParameterJdbcTemplate jdbcTemplate;
private SimpleJdbcInsert jdbcInviteInsert;
private SimpleJdbcInsert jdbcChallengeInsert;

this.jdbcInviteInsert = new SimpleJdbcInsert(dataSource).withTableName("invite_contact").usingGeneratedKeyColumns("id");
this.jdbcChallengeInsert = new SimpleJdbcInsert(dataSource).withTableName("challenge").usingGeneratedKeyColumns("id");
this.jdbcPreferenceInsert = new SimpleJdbcInsert(dataSource).withTableName("preference").usingGeneratedKeyColumns("id");
this.jdbcPostitInsert = new SimpleJdbcInsert(dataSource).withTableName("account_postit");
}
// super-awesome-revolutionary code
}
如果我需要提供任何其他信息，请告诉我:)
根本原因是
没有定义名为 'dataSourceSlave' 的 bean
似乎在服务内部某处您通过这个名称引用它，而数据源 bean 是用名称 'dataSource' 创建的。
检查你的 servlet-context.xml 看看你是否正在扫描控制器所在的包，然后检查你是否有这样的东西：
<context:component-scan base-package="your/package/path/controllers"/>
your/package/path/controllers 是你的控制器 class 所在的地方。
DriverManagerDataSurce 不提供池功能。它没有定义属性 acquireIncrement、idleConnectionTestPeriod、maxPoolSize、maxStatements 和 minPoolSize。
要么删除这些属性，要么使用支持池的数据源，例如 apache commons-dbcp BasicDataSource。不建议在生产系统中使用 DriverManagerDataSurce。其用于测试目的。
例如
<bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource" destroy-method="close">
<property name="driverClassName" value="${jdbc.driverClassName}"/>
<property name="url" value="${jdbc.url}"/>
<property name="username" value="${jdbc.username}"/>
<property name="password" value="${jdbc.password}"/>
<property name="maxActive" value="100"/>
</bean>
