.每個方法介面要打註釋.

1.配置：本地mysql（Linux虛擬機器mysql）建表test資料庫goods表，IDEA。

2.執行：例：http://localhost:9090/goods/update?id=1&name=b&price=1000&amount=8&sum=5000

3.報錯：某異常：No operations allowed after connection closed，解決辦法：刪除 DbUtil.closeConnection(con);DbUtil.closePreparedStatement(ps);這兩行。

4.配置檔案resources：

server.port=9090

################################   logger ?####################
log4j.rootLogger=info,ServerDailyRollingFile,stdout

log4j.appender.ServerDailyRollingFile=org.apache.log4j.DailyRollingFileAppender
log4j.appender.ServerDailyRollingFile.DatePattern='.'yyyy-MM-dd
log4j.appender.ServerDailyRollingFile.File=D://test/test.log
log4j.appender.ServerDailyRollingFile.layout=org.apache.log4j.PatternLayout
log4j.appender.ServerDailyRollingFile.layout.ConversionPattern=%d{yyyy-MM-dd HH:mm:ss} [%t] %-5p [%c] - %m%n
log4j.appender.ServerDailyRollingFile.Append=true

log4j.appender.stdout=org.apache.log4j.ConsoleAppender
log4j.appender.stdout.layout=org.apache.log4j.PatternLayout
log4j.appender.stdout.layout.ConversionPattern=%d yyyy-MM-dd HH:mm:ss %p [%c] %m%n
