项目启动，仅报错 One or more listeners failed to start,控制台没有详细的报错信息

解决方案

• 在classpath下配置logging.properties,内容如下:

  handlers = org.apache.juli.FileHandler, java.util.logging.ConsoleHandler

  ############################################################

  Handler specific properties.

  Describes specific configuration info for Handlers.

  ############################################################

  org.apache.juli.FileHandler.level = FINE
  org.apache.juli.FileHandler.directory = ../logs
  org.apache.juli.FileHandler.prefix = error-debug.

  java.util.logging.ConsoleHandler.level = FINE
  java.util.logging.ConsoleHandler.formatter = java.util.logging.SimpleFormatter

• 配置完成后,控制台显示详细的报错信息

• 根据报错信息,在BaseDictDao.xml中,发现namespace路径是com.com.boot.dao.BaseDictDao

  <mapper namespace="com.com.boot.dao.BaseDictDao">
  <select id="getDictListByTypeCode" parameterType="string" resultType="BaseDict">
  SELECT * FROM base_dict WHERE dict_type_code=#{typeCode}
  </select>
  </mapper>

• 原因是之前修改了包名,然后xml文件的namespace自动修改了

• 把路径修改回正确的路径com.boot.dao.BaseDictDao,然后项目正常启动
