我正在开发我的第一个Hibernate项目，这是一个基于JAX-RS Jersey的Web服务，使用Hibernate+Postgres作为后端运行在Tomcat 8.5上。当我启动Tomcat并尝试通过访问http://localhost:8080/myapp/webapi/users来访问用户资源时，我遇到了以下错误：

我的PostgreSQL服务器运行在本地主机上，我可以从shell连接到它，如下图所示：

但是，在eclipse中，我遇到了上面的错误。我的Hibernate配置文件如下：
<?xml version="1.0" encoding="utf-8"?>
<!DOCTYPE hibernate-configuration SYSTEM 
"http://www.hibernate.org/dtd/hibernate-configuration-3.0.dtd">

<hibernate-configuration>
    <session-factory>
        <!-- connection settings -->
        <property name="hibernate.connection.driver_class">org.postgresql.Driver</property>
        <property name="hibernate.connection.url">jdbc:postgresql://localhost:5432/postgres></property>
        <property name="hibernate.connection.username">postgres</property>
        <property name="hibernate.connection.password">password</property>

        <!-- sql dialect -->
        <property name="hibernate.dialect">org.hibernate.dialect.PostgreSQLDialect</property>
    </session-factory>
</hibernate-configuration>

您在hibernate.connection.url行中有未成对的标签（>）。

免责声明：我的答案与其他可能存在的错误无关。

我不理解你的意思。你指的是哪些标签？ - kovac
你的连接字符串是 jdbc:postgresql://localhost:5432/postgres>，应该是 jdbc:postgresql://localhost:5432/postgres。 - Shiva
一个 > 字符 - Jacek Cz
真是该死，刚看到了...非常感谢您如此仔细地检查它...我花了很长时间。 - kovac
