Question

xml中的Spring配置

<jee:jndi-lookup id="datas1" expected-type="javax.sql.DataSource"
    jndi-name="java:/jndi1" />

<jee:jndi-lookup id="datas2" expected-type="javax.sql.DataSource" 
    jndi-name="java:/jndi2" />

<bean id="EntityM"
    class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean">
    <property name="dataSource" ref="datas1" />
    <property name="packagesToScan" value="package.persistence.entity" />
    <property name="jpaVendorAdapter">
        <bean class="org.springframework.orm.jpa.vendor.HibernateJpaVendorAdapter">
            <property name="showSql" value="true" />
            <property name="generateDdl" value="false" />
            <property name="databasePlatform" value="org.hibernate.dialect.Oracle12cDialect" />
        </bean>
    </property>
</bean>

<bean id="txManager" class="org.springframework.orm.jpa.JpaTransactionManager">
    <property name="entityManagerFactory" ref="EntityM" />
</bean>

The Excpetion是：

上下文初始化失败：org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'springSessionJdbcOperations' defined in class path resource [org/springframework/session/jdbc/config/annotation/web/http/JdbcHttpSessionConfiguration.class]: Unsatisfied dependency expressed through method 'springSessionJdbcOperations' parameter 0: No qualifying bean of type [javax.sql.DataSource] is defined: expected single matching bean but found 2: datas1,datas2; nested exception is org.springframework.beans.factory.NoUniqueBeanDefinitionException: No qualifying bean of type [javax.sql.DataSource] is defined: expected single matching bean but found 2: datas1,jndi2.

我不能配置两个数据源，第一个数据源是entityManagar，第二个数据源是调用存储过程。

Answer 1

JdbcSessionConfiguration需要一个名为'dataSource'的'DataSource'类型的bean。如果找不到，spring尝试使用'DataSource'类型的bean，忽略名称。因为有这种类型的两个bean，所以会抛出异常。

解决方案： 重命名要与EntityManager一起使用的DataSource bean 'datas1'到'dataSource'。

Spring应该能够创建JdbcSessionConfiguration，你可以根据需要使用'datas2'。
