java - spring boot 配置 logback 启动错误

Question

我使用的是spring-boot 1.3 logback-1.1.5 版本
首先是boot配置

# Mysql
spring.datasource.driverClassName = com.mysql.jdbc.Driver
spring.datasource.url = jdbc:mysql://localhost:3306/test2?createDatabaseIfNotExist=true
spring.datasource.username = root
spring.datasource.password = root

# jpa
spring.jpa.database = MYSQL
spring.jpa.show-sql = true
spring.jpa.hibernate.ddl-auto = update
spring.jpa.hibernate.naming-strategy = org.hibernate.cfg.ImprovedNamingStrategy
spring.jpa.properties.hibernate.dialect = org.hibernate.dialect.MySQL5Dialect

## log
logging.level.com.trs.trsirp = DEBUG
#logging.file = logs/logback.log

接下来是logback配置：

<?xml version="1.0" encoding="UTF-8"?>
<configuration debug="false">
    <!--定义日志文件的存储地址 勿在 LogBack 的配置中使用相对路径 -->
    <!--<property name="LOG_HOME" value="/home" />-->
    <!-- 控制台输出 -->
    <!--<appender name="STDOUT" class="ch.qos.logback.core.ConsoleAppender">-->
        <!--<encoder class="ch.qos.logback.classic.encoder.PatternLayoutEncoder">-->
            <!--&lt;!&ndash;格式化输出,%d:日期;%thread:线程名;%-5level：级别,从左显示5个字符宽度;%msg:日志消息;%n:换行符 &ndash;&gt;-->
            <!--<pattern>%d{yyyy-MM-dd HH:mm:ss.SSS} [%thread] %-5level %logger{50} - -->
                <!--%msg%n</pattern>-->
        <!--</encoder>-->
    <!--</appender>-->

    <!-- show parameters for hibernate sql 专为 Hibernate 定制 -->
    <logger name="org.hibernate.type.descriptor.sql.BasicBinder"
        level="TRACE" />
    <logger name="org.hibernate.type.descriptor.sql.BasicExtractor"
        level="DEBUG" />
    <logger name="org.hibernate.SQL" level="DEBUG" />
    <logger name="org.hibernate.engine.QueryParameters" level="DEBUG" />
    <logger name="org.hibernate.engine.query.HQLQueryPlan" level="DEBUG" />

    <!--日志异步到数据库 -->
    <appender name="DB" class="ch.qos.logback.classic.db.DBAppender">
        <!--日志异步到数据库 -->
        <connectionSource class="ch.qos.logback.core.db.DriverManagerConnectionSource">
            <!--连接池 -->
            <dataSource class="com.mchange.v2.c3p0.ComboPooledDataSource">
                <driverClass>com.mysql.jdbc.Driver</driverClass>
                <url>jdbc:mysql://localhost:3306/test2</url>
                <user>root</user>
                <password>root</password>
            </dataSource>
        </connectionSource>
    </appender>

    <!-- 日志输出级别 -->
    <root level="INFO">
        <!--<appender-ref ref="STDOUT" />-->
        <appender-ref ref="DB" />
    </root>

</configuration>

在接下来是报错：

Exception in thread "main" java.lang.IllegalStateException: Logback configuration error detected: 
ERROR in ch.qos.logback.core.joran.spi.Interpreter@28:66 - no applicable action for [dataSource], current ElementPath  is [[configuration][appender][connectionSource][dataSource]]

如果把配置里面的

dataSource 

去掉就可以运行，但是为什么加上就出现这样的错误 ？
第二个问题就是如果把

root 标签的level改成debug

启动就会卡在spring-boot 1.3 启动最开始有一个图案那就地方，不会往下执行 ，这是为什么 ？

Answer 1

The connectionSource configuration is wrong. The class you configured does not support datasource configuration. If you want to support it, you can change it to

ch.qos.logback.core.db.DataSourceConnectionSource
