我想把SQL语句记录到一个文件中。

我在application.properties中有以下属性:

spring.datasource.url=...
spring.datasource.username=user
spring.datasource.password=1234
spring.datasource.driver-class-name=net.sourceforge.jtds.jdbc.Driver

spring.jpa.show-sql=true
spring.jpa.properties.hibernate.format_sql=true

security.ignored=true
security.basic.enabled=false

logging.level.org.springframework.web=INFO
logging.level.org.hibernate=INFO
logging.file=c:/temp/my-log/app.log

当我运行程序时,

cmd> mvn spring-boot:run

我可以在控制台中看到SQL语句,但它们没有出现在app.log中。该文件只包含Spring的基本日志。

我应该怎么做才能在日志文件中看到SQL语句?


当前回答

将这些添加到属性中。引用Hibernate Show SQL:

# Show SQL statement
logging.level.org.hibernate.SQL=debug

# Show SQL values
logging.level.org.hibernate.type.descriptor.sql=trace

其他回答

如果要查看实际使用的参数,可以使用查询

logging.level.org.hibernate.SQL=DEBUG
logging.level.org.hibernate.type.descriptor.sql=TRACE

然后注意,实际的参数值显示为绑定参数…:

    2018-08-07 14:14:36.079 DEBUG 44804 --- [           main] org.hibernate.SQL                        : select employee0_.id as id1_0_, employee0_.department as departme2_0_, employee0_.joining_date as joining_3_0_, employee0_.name as name4_0_ from employee employee0_ where employee0_.joining_date=?
     2018-08-07 14:14:36.079 TRACE 44804 --- [           main] o.h.type.descriptor.sql.BasicBinder      : binding parameter [1] as [TIMESTAMP] - [Tue Aug 07 00:00:00 SGT 2018]

您可以简单地在应用程序中添加以下行。属性为stdout SQL查询:

spring.jpa.properties.hibernate.show_sql=true

根据文档,它是:

spring.jpa.show-sql=true # Enable logging of SQL statements.

在应用程序中添加spring.jpa.properties.hibernate.show_sql=true。属性并不总是有帮助。

您可以尝试添加properties.put(“hibernate。show_sql”、“真正的”);到数据库配置的属性。

public class DbConfig {

    @Primary
    @Bean(name = "entityManagerFactory")
    public LocalContainerEntityManagerFactoryBean
    entityManagerFactory(
            EntityManagerFactoryBuilder builder,
            @Qualifier("dataSource") DataSource dataSource
    ) {
        Map<String, Object> properties = new HashMap();
        properties.put("hibernate.hbm2ddl.auto", "validate");
        properties.put("hibernate.show_sql", "true");

        return builder
                .dataSource(dataSource)
                .packages("com.test.dbsource.domain")
                .persistenceUnit("dbsource").properties(properties)
                .build();
    }

在我的YAML文件:

logging:
  level:
    org.hibernate.SQL: DEBUG
    org.hibernate.type.descriptor.sql: TRACE

Spring Boot版本:2.3.5.RELEASE
