我正在对this tutorial之后的模型进行查询搜索：
现在一切正常，但是我在日期字段上遇到了一个大问题。当我尝试查询日期时出现错误：
Parameter value [1965-01-01] did not match expected type [java.util.Date (n/a)]; nested exception is java.lang.IllegalArgumentException: Parameter value [1965-01-01] did not match expected type [java.util.Date (n/a)]
我如何使其工作？

这是发生错误时的堆栈跟踪
java.lang.IllegalArgumentException: Parameter value [2019-01-01] did not match expected type [java.util.Date (n/a)]

这是AnagraficaController.findAllByRsql中的代码
@RequestMapping(method = RequestMethod.POST, value = "/cerca")
@ResponseBody
public List<Anagrafica> findAllByRsql(@RequestBody @Valid SearchPatternRequest requests) {
if (requests.getSearchPattern() != null) {
Node rootNode = new RSQLParser().parse(requests.getSearchPattern());
Specification<Anagrafica> spec = rootNode.accept(new CustomRsqlVisitor<Anagrafica>());
return repository.findAll(spec);
} else {
return repository.findAll();
}
}
另外，如果有帮助的话，这是搜索模式： “ lastname == ALF *; dob> 2019-01-01”

CustomRsqlVisitor看起来像这样：
public class CustomRsqlVisitor<T> implements RSQLVisitor<Specification<T>, Void> {
private GenericRsqlSpecBuilder<T> builder;
public CustomRsqlVisitor() {
builder = new GenericRsqlSpecBuilder<T>();
}
@Override

}
@Override
public Specification<T> visit(final OrNode node, final Void param) {
return builder.createSpecification(node);
}
@Override
public Specification<T> visit(final ComparisonNode node, final Void params) {
return builder.createSpecification(node);

GenericRsqlSpecBuilder在这里：

.stream()
.map(node -> createSpecification(node))
.filter(Objects::nonNull)
.collect(Collectors.toList());
Specification<T> result = specs.get(0);
if (logicalNode.getOperator() == LogicalOperator.AND) {
for (int i = 1; i < specs.size(); i++) {
result = Specification.where(result).and(specs.get(i));
}
}
else if (logicalNode.getOperator() == LogicalOperator.OR) {
for (int i = 1; i < specs.size(); i++) {
result = Specification.where(result).or(specs.get(i));
}
}
return result;

public Specification<T> createSpecification(final ComparisonNode comparisonNode) {
