我正在尝试用Postgres编写Spring Data JPA应用程序。
我收到错误：FATAL: password authentication failed for user
我尝试使用常规JDBC编写连接时使用相同的东西，并且所有工作正常，相同的用户名/密码/数据库/主机名。
我用于Spring Data JPA的属性文件包含以下内容：
spring.jpa.database=POSTGRESQL
spring.datasource.platform=postgres
spring.jpa.show-sql=true
spring.jpa.hibernate.ddl-auto=create-drop
spring.database.driverClassName=org.postgresql.Driver
spring.datasource.url=jdbc:postgresql://localhost:5432/testdb
spring.datasource.username=test_java
spring.datasource.password=easy_password
server.port=8080
与我用于java jdbc测试的属性文件相比：
db.url=jdbc:postgresql://localhost:5432/testdb
db.user=test_java
db.passwd=easy_password
Java代码如下所示：
public void testSelectWithPropertyFile() {
Logger lgr = Logger.getLogger(getClass().getName());
Connection con = null;
PreparedStatement pst = null;
ResultSet rs = null;
Properties props = new Properties();
FileInputStream in = null;
try {
in = new FileInputStream("target/classes/properties/database.properties");
props.load(in);
} catch (IOException ex) {
lgr.log(Level.SEVERE, ex.getMessage(), ex);
return;
} finally {
try {
if (in != null) {
in.close();
}
} catch (IOException ex) {
lgr.log(Level.SEVERE, ex.getMessage(), ex);
}
}
String url = props.getProperty("db.url");
String user = props.getProperty("db.user");
String passwd = props.getProperty("db.passwd");
try {
con = DriverManager.getConnection(url, user, passwd);
pst = con.prepareStatement("SELECT * FROM Authors");
rs = pst.executeQuery();
while (rs.next()) {
System.out.print(rs.getInt(1));
System.out.print(": ");
System.out.println(rs.getString(2));
}
} catch (Exception ex) {
lgr.log(Level.SEVERE, ex.getMessage(), ex);
} finally {
try {
if (rs != null) {
rs.close();
}
if (pst != null) {
pst.close();
}
if (con != null) {
con.close();
}
} catch (SQLException ex) {
lgr.log(Level.WARNING, ex.getMessage(), ex);
}
}
}
这是我在Spring Boot JPA中得到的错误日志：

我无法理解Spring数据JPA如何在普通的Java JDBC工作正常时无法进行身份验证。

您的问题是身份验证，

用户＆＃34; test_java＆＃34;
的密码验证失败
确定此信息连接正确吗？因为那是你的问题 如果是正确的，那么进行测试，连接你的基地中的同一个其他客户端，与本地。
请参阅：我文件配置的那部分：
# IPv4 local connections:
host all all 127.0.0.1/32 md5
host all all 192.168.2.0/24 md5

将spring.database.driverClassName=org.postgresql.Driver替换为
spring.datasource.driverClassName=org.postgresql.Driver
