In my Spring boot(2.0.7 RELEASE) application I am not able to manually set/override the timeout for the database connections in the application.properites file. I am using JPA, Hibernate, Tomcat connection pool and Postgres.
I've researched thoroughly and found very similar questions :
The reason I ask new question is because neither of the questions above have an accepted answer nor a confirmed working solution. I tried including each proposed solution in my application.properties file with no success.
Also, as mentioned in question 2: if I add parameter 'timeout = someSeconds' in the @Transactional annotation, the connection timeouts as expected but if I try extracting it in the application.properties it fails and timeouts for the default time. The problem here is that I want all connections to timeout in the given time not only the transactions.
Things I've tried in the application.properties (The desired timeout is 4 seconds):
Materials I've read:
Am I missing some property? Does anyone know why the timeout can't be overridden via the application.properties file?
Thanks in advance.
There are at least 3 time-outs to configure:
txManager.setDefaultTimeout(myDefaultValue);
Query timeouts(which obviously does not need @transactional), which you already did and also explained here
Network timeouts(Read this excellent article ).
For my case, i am using Oracle, and my bean configuration is as follows:
@Bean
public HikariDataSource dataSource() {
HikariDataSource ds = new HikariDataSource();
ds.setDriverClassName(springDatasourceDriverClassName);
ds.setJdbcUrl(springDatasourceUrl);
ds.setUsername(springDatasourceUsername);
ds.setPassword(springDatasourcePassword);
ds.setDataSourceProperties(oracleProperties());
return ds;
}
Properties oracleProperties() {
Properties properties = new Properties();
properties.put("oracle.net.CONNECT_TIMEOUT", 10000);
properties.put("oracle.net.READ_TIMEOUT", 10000);
properties.put("oracle.jdbc.ReadTimeout", 10000);
return properties;
}
And if you do not want to configure a bean for the DataSource(which is what most people will do), you can configure the network timeout properties in application.properties:
spring.datasource.hikari.data-source-properties.oracle.net.CONNECT_TIMEOUT=10000
spring.datasource.hikari.data-source-properties.oracle.net.READ_TIMEOUT=10000
spring.datasource.hikari.data-source-properties.oracle.jdbc.ReadTimeout=10000
Depending on your datasource, but you can try this:
spring.datasource.hikari.max-lifetime=1000
spring.datasource.hikari.connection-timeout=1000
spring.datasource.hikari.validation-timeout=1000
spring.datasource.hikari.maximum-pool-size=10
