在grails 2.4中获取IllegalArgumentException

标签： mysql grails gorm

我按照grails页面中的映射说明操作： http://docs.grails.org/latest/ref/Database%20Mapping/id.html

域类：CategoryType.groovy 

class CategoryType {

static constraints = {

}

String value 

static mapping = { 
    version false 
    id column: 'id', type: 'integer'
}
}

Controller类：CategoryTypeController，我有一个函数：

def getAll() {
    def s = CategoryType.list()
    render s as JSON
}

数据库是Mysql，表category_type的id是INT（11）。 毕竟，我运行应用程序并且根本没有编译错误，但是在视图中，如果我调用函数getAll（），则会抛出错误，如下所示：

property.BasicPropertyAccessor HHH000123: IllegalArgumentException in class: 

com.pti.backend.CategoryType, setter method of property: id
property.BasicPropertyAccessor HHH000091: Expected type: java.lang.Long, actual value: java.lang.Integer
errors.GrailsExceptionResolver IllegalArgumentException occurred when processing request: [POST] /learning/categoryType/getAll
argument type mismatch. Stacktrace follows:

请帮助我，我尝试了很多不同的方法，但它不起作用。 感谢。

2 个答案:

答案 0 :(得分：2)

您应该明确指定id的类型：

class CategoryType {
  Integer id
  //...
}

答案 1 :(得分：1)

我建议你只是从映射闭包中删除与id相关的东西。它将自动映射到Long类型和“id”列。
