Spring boot application.properties hibernate.generate_statistics
Solution 1
Not sure if the below is correct, but got it working.
I'm forcing the properties onto my LocalContainerEntityManagerFactoryBean
with construction.
DatabaseConfig snippet:
@Configuration
@EnableTransactionManagement
@ConfigurationProperties(prefix = "spring.datasource")
public class DatabaseConfig extends HikariConfig {
@Autowired
@Bean
public LocalContainerEntityManagerFactoryBean entityManagerFactory(DataSource dataSource, Environment env) {
LocalContainerEntityManagerFactoryBean entityManagerFactory = new LocalContainerEntityManagerFactoryBean();
entityManagerFactory.setDataSource(dataSource);
// Classpath scanning of @Component, @Service, etc annotated class
entityManagerFactory.setPackagesToScan(new String[]{"com.test"});
// Vendor adapter
HibernateJpaVendorAdapter vendorAdapter = new HibernateJpaVendorAdapter();
entityManagerFactory.setJpaVendorAdapter(vendorAdapter);
Properties jpaProperties = new Properties();
jpaProperties.put("hibernate.show_sql",
env.getRequiredProperty("spring.jpa.properties.hibernate.show_sql")
);
jpaProperties.put("hibernate.format_sql",
env.getRequiredProperty("spring.jpa.properties.hibernate.format_sql")
);
jpaProperties.put("hibernate.generate_statistics",
env.getRequiredProperty("spring.jpa.properties.hibernate.generate_statistics")
);
entityManagerFactory.setJpaProperties(jpaProperties);
return entityManagerFactory;
}
}
After the config
2017-03-16 11:41:02.881 DEBUG 7884 --- [main] o.h.s.internal.ConcurrentStatisticsImpl : HHH000117: HQL: select up from UserPlan up, time: 48ms, rows: 1

}
Solution 2
It works for me (using Spring Boot 2.1.6.RELEASE).
a) In file application.properties:
spring.jpa.properties.hibernate.generate_statistics=true
b) Ensure runtime debug level for 'org.hibernate.stat' is at least DEBUG:
curl -i -X POST -H 'Content-Type: application/json' -d '{"configuredLevel": "DEBUG"}' http://localhost:8080/actuator/loggers/org.hibernate.stat
c) Check in log something like:
2019-07-03 21:27:27.739 DEBUG 11797 --- [nio-8080-exec-3] o.h.stat.internal.StatisticsImpl : HHH000117: HQL: select count(*) from AppRequest x WHERE x.uuid = :uuid, time: 1ms, rows: 1
Solution 3
Define property hibernate.generate_statistics=true
in hibernate.properties
file.

Trying to be a better... @Autowired public Person(Developer developer) { this.developer = developer; }

After following various examples and reading the spring boot documentation I'm still unable to enable hibernate statistics. I'm setting the property in the application.properties file. Running the spring boot application via a integration test or
Application.java
produces no stats.My
application.properties
file.spring.datasource.jdbcUrl=jdbc:postgresql://localhost:5432/postgres spring.datasource.username = postgres spring.datasource.password = password spring.datasource.driver-class-name=org.postgresql.Driver spring.datasource.platform=postgres spring.datasource.testWhileIdle = true spring.datasource.validationQuery = SELECT 1 spring.jpa.properties.hibernate.show_sql=true spring.jpa.properties.hibernate.format_sql=true spring.jpa.properties.hibernate.generate_statistics=true logging.level.org.hibernate.SQL=TRACE logging.level.org.hibernate.stat=TRACE logging.file=transaction-app.log
logback-spring.xml
<?xml version="1.0" encoding="UTF-8"?> <configuration> <include resource="org/springframework/boot/logging/logback/defaults.xml" /> <property name="LOG_FILE" value="${LOG_FILE:-${LOG_PATH:-${LOG_TEMP:-${java.io.tmpdir:-/tmp}}/}spring.log}"/> <include resource="org/springframework/boot/logging/logback/file-appender.xml" /> <root level="INFO"> <appender-ref ref="FILE" /> </root> </configuration>
And my integration test
@RunWith(SpringRunner.class) @SpringBootTest(webEnvironment = SpringBootTest.WebEnvironment.RANDOM_PORT) public class SqlMappingTest { @Autowired PlanService planService; @org.junit.Test public void findAll() { List<Plan> plans = planService.findAll(); Assert.assertEquals(1, plans.size()); } }
What am I missing?

Patronaut almost 5 yearsJust for completenes, all the settings from different sources influencing hibernate can be accessed via the classpath "org.hibernate.cfg.Environment."

Alex Pritchard about 4 yearsHey thanks for this. I looked at half a dozen answers before I realized I needed spring.jpa.properties.hibernate.generate_statistics and not just hibernate.generate_statistics in my app.properties file.
