Spring的Logger配置和中文乱码问题

环境：Window10（默认语言为英文）

springframeworl 4.3.0.RELEASE

控制台mvn tomcat7:run启动项目

pom.xml关键部分

这里因为activemq带了slf4j，org.spdlat中引入了slf4j-api和logback-classic，所以不需要另外引入slf4j和log4j，如果需要的话引入slf4j-api

运行项目显示绑定的是log4j

SLF4J: Class path contains multiple SLF4J bindings.SLF4J: Found binding in [jar:file:/C:/Users/i332390/.m2/repository/org/apache/activemq/activemq-all/5.9.0/activemq-all-5.9.0.jar!/org/slf4j/impl/StaticLoggerBinder.class]SLF4J: Found binding in [jar:file:/C:/Users/i332390/.m2/repository/ch/qos/logback/logback-classic/0.9.28/logback-classic-0.9.28.jar!/org/slf4j/impl/StaticLoggerBinder.class]SLF4J: See http://www.slf4j.org/codes.html#multiple_bindings for an explanation.SLF4J: Actual binding is of type [org.slf4j.impl.Log4jLoggerFactory]Sep 27, 2017 4:39:27 PM org.apache.catalina.core.ApplicationContext log

在src/main/resources下创建log4j.xml （appender的encoding为第一个关键点）

<?xml version="1.0" encoding="utf-8" ?><!DOCTYPE log4j:configuration PUBLIC "-//log4j/log4j Configuration//EN" "log4j.dtd"><log4j:configuration>  <appender name="STDOUT" class="org.apache.log4j.ConsoleAppender">    <param name="encoding" value="UTF-8" />    <layout class="org.apache.log4j.PatternLayout">      <param name="ConversionPattern" value="[%d{HH:mm:ss:SSS}] [%p] - %l - %m%n"/>    </layout>  </appender>  <logger name="com.sap.c4c.wechat.web.PublicAccountController">    <level value="debug"/>    <appender-ref ref="STDOUT" />  </logger>  <logger name="com.sap.c4c.wechat.service">    <level value="debug"/>    <appender-ref ref="STDOUT" />  </logger>  <!-- Strictly speaking, the level attribute is not necessary since -->  <!-- the level of the root level is set to DEBUG by default.       -->  <root>    <level value="info"/>    <appender-ref ref="STDOUT" />  </root></log4j:configuration>

使用时引入 org.slf4j.Logger和org.slf4j.LoggerFactory

private static final Logger logger = LoggerFactory.getLogger(YourClass.class.getName());logger.info("输出");

cmd控制台执行

chcp 65001

设置属性，选择合适的字体，比如

这时可以看到编码

此时，原来显示为???或者乱码的中文能正确显示

对于http请求的中文乱码，设置Content-Type为application/json;charset=UTF-8

对于http回复的中文乱码，在servlet配置中可以这样写

    <mvc:annotation-driven>        <mvc:message-converters>            <bean class="org.springframework.http.converter.StringHttpMessageConverter" >                <property name="supportedMediaTypes" value="application/json;charset=UTF-8"/>            </bean>        </mvc:message-converters>    </mvc:annotation-driven>
