I had a simple query like:

select * from sometable where date = ?

I injected a LocalDate into query:

jdbcTemplate.query(QUERY, date);

Everything worked fine. After I moved my project with IDE to another PC, without any alterations, it started to throw exception:

nested exception is org.postgresql.util.PSQLException: 
Can't infer the SQL type to use for an instance of java.time.LocalDate. 
Use setObject() with an explicit Types value to specify the type to use.

I can use a workaround via converting LocalDate to Date:

jdbcTemplate.query(QUERY, java.sql.Date.valueOf(date));

but it does not seem right to me: I want to know the reason. What I checked so far:

1. PostgreSQL version is the same (BTW tried upgrading to 14)
2. JDK version is the same
3. POM dependency for PostgreSQL is the same.

CodePudding user response：

java.time.LocalDate has been available since Java-8 whereas your JDBC driver is based on Java-7, and hence the problem. Upgrade the JDBC driver to the latest one (following) or at least to the one supporting minimum Java-8.

<!-- https://mvnrepository.com/artifact/org.postgresql/postgresql -->
<dependency>
    <groupId>org.postgresql</groupId>
    <artifactId>postgresql</artifactId>
    <version>42.2.24</version>
</dependency>

Note: The java.util Date-Time API and its children are outdated and error-prone. It is recommended to stop using them completely and switch to the modern Date-Time API^*.

^{* If you are working for an Android project and your Android API level is still not compliant with Java-8, check Java 8 APIs available through desugaring. Note that Android 8.0 Oreo already provides support for java.time.}
