idea关闭web3j的debug日志

在使用java的web3j库时，http访问会输出较多如下的日志内容，严重影响终端的其他输出信息。

14:26:48.572 [main] DEBUG org.web3j.protocol.http.HttpService - <-- END HTTP (40-byte body)
14:26:48.588 [pool-1-thread-1] DEBUG org.web3j.protocol.http.HttpService - --> POST http://192.168.56.118:8545/

14:26:48.591 [pool-1-thread-1] DEBUG org.web3j.protocol.http.HttpService - 
14:26:48.595 [pool-1-thread-1] DEBUG org.web3j.protocol.http.HttpService - {"jsonrpc":"2.0","id":1,"result":"0x1"}

如何关闭：已maven项目为例，在/src/main/resources/目录下，创建logback.xml文件即可搞定，文件内容如下：

<?xml version="1.0" encoding="UTF-8"?>
<configuration>

    <appender name="STDOUT" class="ch.qos.logback.core.ConsoleAppender">
        <encoder>
            <pattern>%d{HH:mm:ss.SSS} [%thread] %-5level %logger{36} - %msg%n</pattern>
        </encoder>
    </appender>

    <!-- Change to DEBUG to log protocol messages -->
    <logger name="org.web3j.protocol" level="INFO"/>

    <root level="INFO">
        <appender-ref ref="STDOUT"/>
    </root>
</configuration>
