想用springboot整合optaplanner的vrp模型，尝试好多次，感觉根源在sortEntityClassList为空，solverConfig读取的vrp模型的实体类测试都为空。

solver-config-xml: com/optTool/core/vehiclerouting/vehicleRoutingSolverConfig.xml

配置里面一加这个solver-config-xml就启动失败报错~~~

导入依赖：

<dependency>
   <groupId>org.optaplanner</groupId>
   <artifactId>optaplanner-spring-boot-starter</artifactId>
   <version>8.30.0.Final</version>
</dependency>

配置yml：

optaplanner:
  solver:
    termination:
      spent-limit: 3s
      unimproved-spent-limit: 5s
  solver-config-xml: com/optTool/core/vehiclerouting/vehicleRoutingSolverConfig.xml

然后启动就报错：
