JPA print sql and parameter settings

A. Jpa how to print sql statement?

Now most of the online approach is: add properties file: spring.jpa.show-sql = true.

Could it? Yes, however the system is printed with System.out.println method, bad management.

 

I would like to set up how to use the picture log 1 print it?

Logback.xml added in the <logger name = "org.hibernate.SQL" level = "DEBUG" /> it.

Two .jpa how to print parameter?

The above configuration, only print sql statement, sql parameters required in no output come out.

<logger name="org.hibernate.type.descriptor.sql.BasicBinder" level="trace" />

Added to the upper logger configuration, you can print the sql parameter.

Three .jpa select statement prints super much, I do not want to see select sql statement how to do?

Appender added to the output of the line filter.

<appender name="CONSOLE" class="ch.qos.logback.core.ConsoleAppender">
    <filter class="ch.qos.logback.core.filter.EvaluatorFilter">
        <evaluator> <!-- defaults to type ch.qos.logback.classic.boolex.JaninoEventEvaluator -->
            <expression>return message.contains("select");</expression>
        </evaluator>
        <OnMismatch>NEUTRAL</OnMismatch>
        <OnMatch>DENY</OnMatch>
    </filter>
    <encoder>
        <pattern>${CONSOLE_LOG_PATTERN}</pattern>
        <charset>utf8</charset>
    </encoder>
</appender>

Add this filter should also requires the introduction of a jar, otherwise start error.
