OptaPlanner执行服务器无法将string（）转换为type（java.time.LocalDateTime）

时间：2018-01-10 03:20:28

标签： rest optaplanner

尝试设置员工排班＆＃34;试用样品＆＃34;来自Workbench并尝试通过REST API访问解决方案。 我在使用POST上传我的数据集时遇到了一个问题，我在下面详细列出了我尝试和面对的内容。

在此之前，当我注册（PUT）我的求解器config.xml时，我将NOT_SOLVING作为状态。这是我们将获得的实际状态吗？

错误是解析日期格式。

<startTime>2017-01-01T00:00</startTime>

并尝试了不同的格式，如下所示，但它没有帮助。

 <startTime>2017-01-01 00:00</startTime>

环境详情：

wildfly-10.0.0.Final
kie-server(Execution Server) - 7.5.0.Final 
Workbenck(for WildFly10)

PUT：http://localhost:8080/kie-server/services/rest/server/containers/employeerostering/solvers/employeerosteringSolver

RequestBody：

2 个答案:

答案 0 :(得分：0)

问题在于给出了dateformat。我通过反编译导致问题的罐子来完成。

实际上它所期望的日期格式是：

<startTime>2017-01-01T16:00:01.001</startTime>

但我在许多例子中看到的是：

<startTime>2017-01-01T00:00</startTime>

答案 1 :(得分：0)

在Optaplanner 7.9.0上，此示例存在相同的问题，但错误有所不同

  

“处理期间发生意外错误：无法解组输入字符串”

提交的解决方案xml是从这篇jboss文章中复制的（如果使用上述xml，则会出现相同的错误）。
