我正在使用Spring Boot + Spring Batch + myBatis。我们有2个实体（DepartmentEntity，EmpoyeeEntity）/ Department-mapper.xml和Employee-mapper.xml

EmpValidationEntity.java(Employee Entity)
public class EmpValidationEntity{
private empName;
private empDept;
setter/getter 
}    

DepartmentValidationEntity.java(Department Entity)     
public class DeptValidationEntity{
private deptName;
private Dept;
setter/getter 
}

EmpMapper.xml(Employee mapper file-myBatis based)
//select query from Emp

DeptMapper.xml(Department mapper file)
//select query from Dept

EmpInterDependentFieldsValidator.java (Validator class file)

public class EmpInterDependentFieldsValidator
        implements ConstraintValidator<EmpInterDependentFieldsValidation,EmpValidationEntity> {
@Override
    public boolean isValid(SsnValidationEntity value,ConstraintValidatorContext context) {

        Object fieldValue = null;
        boolean isValid = false;

        boolean isFieldValid = true;
        try {
            fieldValue = BeanUtils.getProperty(value,fieldName);
            } 
        catch(Exception e){}
    if (isFieldValid) {
            isValid = validateFields(value,context,fieldValue,fieldName,isValid);
            } else {
            context.disableDefaultConstraintViolation();
            context.buildConstraintViolationWithTemplate(ErrorMessageConstant.INVALID_FIELD)
                    .addPropertyNode(fieldName).addConstraintViolation();
        }
}
return isValid;}



    private boolean validateFields(EmpValidationEntity value,ConstraintValidatorContext context,Object fieldToValid,String fieldName,boolean isValid) {
        String fieldValue = null;


        if (fieldToValid != null) {
            fieldValue = fieldToValid.toString();
        }
        if (fieldName.equalsIgnoreCase("EMPLOYEE_DEPT")) {
            return EmpValidationService.validate(fieldName,value,context);
        }

        return isValid;
    }

}


EmpValidationService.java(validation service class)


public class EmpValidationService{
static List<String> ssnList=null;           
        public static boolean validate(String fieldName,String fieldValue,EmpValidationEntity entity,ConstraintValidatorContext context) {
            StringBuilder errorMessage = new StringBuilder();
            boolean isValid = true;
    if(departmentList.contains(entity.getEmpdept())){
      errorMessage.append(ErrorMessageConstant.Ssn_ALREADY_TIED_TO_ANOTHER_DOB);}           

}

在上面的课程中，如何获取DepartmentList（在单个加载/转储中）？

从上面的代码中，我想传递两个实体并将两个实体对象数据的范围放入EmpValidationService类，此后，我想将每个实体数据存储到不同的列表中，因为我想检查一个实体数据包含到另一个实体数据中。
