rest-assured 将log()中的信息打印到log日志中去的方法

rest-assured 将log()中的信息打印到log日志中去的方法：

============方法1==============

PrintStream fileOutPutStream = new PrintStream(new File("log/test.log"));

RestAssured.config

= RestAssured.config().logConfig(new LogConfig(fileOutPutStream, true));

============方法2==============

RestAssured.config = RestAssured.config().logConfig(new LogConfig(new ToLoggerPrintStream(logger).getPrintStream(), true));

import java.io.IOException;
import java.io.OutputStream;
import java.io.PrintStream;
import org.slf4j.Logger;

/**
 * A wrapper class which takes a logger as constructor argument and offers a PrintStream whose flush
 * method writes the written content to the supplied logger (debug level).
 * <p>
 * Usage:<br>
 * initializing in @BeforeClass of the unit test:
 * <pre>
 *          ToLoggerPrintStream loggerPrintStream = new ToLoggerPrintStream( myLog );
 *          RestAssured.config = RestAssured.config().logConfig(
 *                                 new LogConfig( loggerPrintStream.getPrintStream(), true ) );
 * </pre>
 * will redirect all log outputs of a ValidatableResponse to the supplied logger:
 * <pre>
 *             resp.then().log().all( true );
 * </pre>
