java - bean 类 [com.zaxxer.hikari.HikariConfig] 的无效属性“url”

Question

我是弹簧框架的新手。我在 spring MVC（版本 4）+ hibernate（版本 4）框架应用程序中使用 Hikari 创建一个连接池。运行我的应用程序时出现以下错误。

 Invalid property 'url' of bean class [com.zaxxer.hikari.HikariConfig]: Bean property 'url' is not writable or has an invalid setter method. Does the parameter type of the setter match the return type of the getter?

调度程序-servelt.xml：

<bean id="dataSource" class="com.zaxxer.hikari.HikariDataSource" destroy-method="close">
            <constructor-arg ref="hikariConfig" />
        </bean>

        <!-- HikariConfig config that is fed to above dataSource -->
        <bean id="hikariConfig" class="com.zaxxer.hikari.HikariConfig">
                <property name="driverClassName" value="${postgres.driver}" />
                <property name="url" value="${postgres.url}?stringtype=unspecified" />
                <property name="username" value="${postgres.user}" />
                <property name="password" value="${postgres.password}" />
                <property name="maximumPoolSize" value="${hikari.maximumPoolSize}" />
                <property name="idleTimeout" value="30000" />
        </bean>

        <bean id="sessionFactory" class="org.springframework.orm.hibernate4.LocalSessionFactoryBean" >
                <property name="dataSource" ref="dataSource" />
                <property name="packagesToScan">

                        <value>XXXX</value>
                    </array>
                </property>
                <property name="hibernateProperties">
