我有：

可正常运行的j2ee应用程序。
通过以下方式在我的项目中增加了jpa的功能：

将persistence.xml添加到META-INF文件夹中，我已经证明可以识别出该persistence.xml。

    <?xml version="1.0" encoding="UTF-8"?>
<persistence version="2.1"
    xmlns="http://xmlns.jcp.org/xml/ns/persistence" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/persistence http://xmlns.jcp.org/xml/ns/persistence/persistence_2_1.xsd">
    <!-- <persistence-unit name="TestPersistence" transaction-type="RESOURCE_LOCAL">-->
    <persistence-unit name="TestPersistence" transaction-type="JTA">
    <!-- <persistence-unit name="TestPersistence">-->
        <!-- <class>javax.persistence.EntityManager</class>-->
        <properties>
            <property name="javax.persistence.jdbc.driver" value="com.mysql.jdbc.Driver" />
            <property name="javax.persistence.jdbc.url" value="jdbc:mysql://localhost:3306/world?serverTimezone=UTC" />
            <property name="javax.persistence.jdbc.user" value="root" />
            <property name="javax.persistence.jdbc.password" value="xxx" />
        </properties>
    </persistence-unit>
</persistence>

我在端口3306上有一个正在运行的mysql数据库。
我已经通过maven依赖项添加了相应的sql jdbc驱动程序。

为什么我的应用程序尝试连接到1527，我该如何解决呢？
