我在引用此查询时遇到问题。在Postgres上，此查询执行时没有错误。在JAVA上，它抛出以下异常：
javax.persistence.PersistenceException: org.hibernate.exception.SQLGrammarException: could not extract ResultSet
cause
org.postgresql.util.PSQLException: ERROR: operator does not exist: uuid = bytea
Note: No operator matches the given name and argument type(s). You might need to add explicit type casts.
Position: 404
我做什么？
我的方法：

我用这个表单解决了我的问题： 我将命令CAST用于我的UUID字段
public List<CivilRecord> dashboardSearch(CivilRecordSearch civilRecordSearch)

StringBuilder query = new StringBuilder();

对Robson Silveira的类似回应。
注意查询字符串的最后一位。
const projectId = 'test-bot-test-1111';
const sessionId = user.uuid;
const languageCode = 'en-GB';
const sessionClient = new dialogFlow.SessionsClient();
const sessionPath = sessionClient.sessionPath(projectId, sessionId);
const request = {
session: sessionPath,
queryInput: {
event: {
name: 'custom_event',
languageCode,
parameters: {
name: 'sam',
user_name: 'sam',
a: 'saaaa'
}
}
},
queryParams: {
payload: {
data: user
}
}
};
let resultReq;
console.log('request :: ', request, '\n\n');
try {
resultReq = await sessionClient.detectIntent(request);
} catch (err) {
// eslint-disable-next-line no-console
return console.error('ERROR:', err);

Hibernate应该将Java UUID类型映射到后端uuid类型。但是，如果休眠不知道如何映射它，它将尝试序列化该对象，从而产生byte[]。当然，这只是将问题转移到数据库级别。 uuid后缀类型的值不能仅与字节数组类型进行比较。
PSQLException: ERROR: operator does not exist: uuid = bytea
从Spring Boot 1.x迁移到Spring Boot 2.3.0时遇到了这个问题。在Spring Boot 1.x中，足以用@Id标记我的id字段并使它们成为Java类型UUID。
一种可能的解决方案是显式声明id字段的PSQL类型。
@Type(type="org.hibernate.type.PostgresUUIDType")
@Id
private UUID id;
更好的解决方案是定义系统范围的替换。您可以将此声明放在任何类或包上。仅在某个位置定义一次会实际上影响所有UUID声明。
@TypeDef(name="postgres-uuid",
defaultForType = UUID.class,
typeClass = PostgresUUIDType.class)
看看您的日志文件，您可能会看到类似的内容。仔细检查该方言的版本，然后查看它是否与您在属性文件中定义的方言匹配：
Dialect - HHH000400: Using dialect: org.hibernate.dialect.PostgreSQL81Dialect
在这种情况下，请注意以下属性已过时：
hibernate.dialect=org.hibernate.dialect.PostgreSQL9Dialect
某些休眠属性现在需要具有spring.jpa.properties前缀。因此，在这种情况下，新的属性路径应为spring.jpa.properties.hibernate.dialect=org.hibernate.dialect.PostgreSQL9Dialect。
这就是一切开始变得有意义的地步。该方言可以为您完成所有必需的类型定义。
