Java 嵌套异常为org.hibernate.exception.sqlgrammareexception:无法提取结果集hibernate+；SpringMVC

我试图从数据库中获取记录，但出现了上述错误

这是我的班级，有合适的接受者和接受者

public class User {
    private int id;
    private String username;
    private String password;
    private String email;

我还创建了数据库，并使用下面的配置将数据插入其中

<bean id="dataSource" class="org.apache.commons.dbcp2.BasicDataSource" destroy-method="close">
        <property name="driverClassName" value="com.mysql.jdbc.Driver"/>
        <property name="url" value="jdbc:mysql://localhost:3306/usersdb"/>
        <property name="username" value="root"/>
        <property name="password" value=""/>
    </bean>   

请问我在SpringMVC和Hibernate上的新功能有什么问题

User.java的完整代码

package net.codejava.spring.model;

public class User {
    private int id;
    private String username;
    private String password;
    private String email;

    public int getId() {
        return id;
    }

    public void setId(int id) {
        this.id = id;
    }

    public String getUsername() {
        return username;
    }

    public void setUsername(String username) {
        this.username = username;
    }

    public String getPassword() {
        return password;
    }

    public void setPassword(String password) {
        this.password = password;
    }

    public String getEmail() {
        return email;
    }

    public void setEmail(String email) {
        this.email = email;
    }

}

您是否创建了“用户”表？若用户类映射到表，则使用注释@Entity和@table（name=“users”）。试试这个。

您创建了“用户”表吗？若用户类映射到表，则使用注释@Entity和@table（name=“users”）。试试这个。

把这个添加到你的课堂上：

@Entity
@Table(name="User") or @Table(name="Users")
public class User

请发布完整的堆栈跟踪。我已添加完整的堆栈跟踪。您确定数据库中存在该表吗。错误提示表不存在。是否可以检查是否有用户作为表名？表名为users请发布完整堆栈跟踪我已添加完整堆栈跟踪。是否确定数据库中存在该表。错误表明表不存在。能否检查是否有一个或多个用户作为表的名称？表名为users此处应添加此项请了解使用注释的pom依赖关系。令牌“annotation”上的语法错误，删除此令牌我是否从令牌entityNo中删除注释。它必须看起来像我在代码中提到的那样，应该在哪里添加这个请确定pom对使用标记“annotation”的annotationSyntax错误的依赖性是什么，删除这个标记我是否从标记entityNo中删除注释。它必须看起来像我在代码中提到的那样
