JavaSpring Boot-使用Oracle Sql实体的问题

Question

我使用Intellij连接到oracle数据库，添加了持久性框架，并通过数据库模式生成持久性映射

package springoraclesql.demo.domain;

import javax.persistence.Basic;
import javax.persistence.Column;
import javax.persistence.Entity;
import javax.persistence.Id;

@Entity
public class Book {
private long bookId;
private String bookName;
private String bookAuthor;
private Long bookPrice;

@Id
@Column(name = "BOOK_ID")
public long getBookId() {
    return bookId;
}

public void setBookId(long bookId) {
    this.bookId = bookId;
}

@Basic
@Column(name = "BOOK_NAME")
public String getBookName() {
    return bookName;
}

public void setBookName(String bookName) {
    this.bookName = bookName;
}

@Basic
@Column(name = "BOOK_AUTHOR")
public String getBookAuthor() {
    return bookAuthor;
}

public void setBookAuthor(String bookAuthor) {
    this.bookAuthor = bookAuthor;
}

@Basic
@Column(name = "BOOK_PRICE")
public Long getBookPrice() {
    return bookPrice;
}

public void setBookPrice(Long bookPrice) {
    this.bookPrice = bookPrice;
}

@Override
public boolean equals(Object o) {
    if (this == o) return true;
    if (o == null || getClass() != o.getClass()) return false;

    Book book = (Book) o;

    if (bookId != book.bookId) return false;
    if (bookName != null ? !bookName.equals(book.bookName) : book.bookName != null) return false;
    if (bookAuthor != null ? !bookAuthor.equals(book.bookAuthor) : book.bookAuthor != null) return false;
    if (bookPrice != null ? !bookPrice.equals(book.bookPrice) : book.bookPrice != null) return false;

    return true;
}

@Override
public int hashCode() {
    int result = (int) (bookId ^ (bookId >>> 32));
    result = 31 * result + (bookName != null ? bookName.hashCode() : 0);
    result = 31 * result + (bookAuthor != null ? bookAuthor.hashCode() : 0);
    result = 31 * result + (bookPrice != null ? bookPrice.hashCode() : 0);
    return result;
}
}

我在java/META-INF下添加了Oracle jdbc和我的persistence.xml，如下所示`

<persistence-unit name="NewPersistenceUnit">
    <class>springoraclesql.demo.domain.Book</class>
    <properties>
        <property name="toplink.jdbc.url" value="jdbc:oracle:thin:@localhost:1521:XE"/>
        <property name="toplink.jdbc.driver" value="oracle.jdbc.OracleDriver"/>
        <property name="hibernate.connection.url" value="jdbc:oracle:thin:@localhost:1521:XE"/>
        <property name="hibernate.connection.driver_class" value="oracle.jdbc.OracleDriver"/>
        <property name="openjpa.ConnectionURL" value="jdbc:oracle:thin:@localhost:1521:XE"/>
        <property name="openjpa.ConnectionDriverName" value="oracle.jdbc.OracleDriver"/>
        <property name="eclipselink.jdbc.url" value="jdbc:oracle:thin:@localhost:1521:XE"/>
        <property name="eclipselink.jdbc.driver" value="oracle.jdbc.OracleDriver"/>
    </properties>
</persistence-unit>

我的application.properties如下所示

oracle.dbsource.url=jdbc:oracle:thin:@localhost:1521:xe
oracle.dbsource.username=talon
oracle.dbsource.password=talon
spring.datasource.url=jdbc:oracle:thin:@localhost:1521:xe
spring.datasource.name=talon
spring.datasource.password=talon
spring.datasource.driver-class-name=oracle.jdbc.driver.OracleDriver
spring.jpa.database-platform=org.hibernate.dialect.Oracle10gDialect

当我运行spring项目时，我有很多java.sql.SQLException:ORA-01017:无效的用户名/密码；拒绝登录错误。但是url、用户名和密码是正确的。

在我尝试使用DriverManager.getConnection连接到同一架构之前，以这种方式检索数据没有任何问题。

Answer 1

我用spring.datasource.name而不是spring.datasource.username
