我正在执行一个看起来有点复杂的 JDOQL 查询：

Query q = pm.newQuery(IxlTest.class, "id == :tId && parameterGroups.get(oGroup.key).contains(tp) && oGroup.contains(opt) && opt.displayInResults");
q.setResult("oGroup, opt");
vars.append(TestTypeOptionsGroup.class.getName() + " oGroup;");
vars.append(TestTypeOption.class.getName() + " opt;");
vars.append(TestParameterGroup.class.getName() + " tpGroup;");
vars.append(TestParameter.class.getName() + " tp;");
q.declareVariables(vars.toString());
System.out.println(q.execute(testId));

我没有理由认为 DN 需要那个Geometry课程，因为我的课程与几何无关。这是parameterGroups映射IxlTest

@Persistent(defaultFetchGroup = "true", table = "ixl_test_parameter_groups_rel")
@Join(column = "test_fk", extensions = { @Extension(vendorName = "datanucleus", key = "primary-key", value = "false") })
@Key(types = { String.class }, column = "test_parameter_group_key", mappedBy = "name", dependent = "true")
@Value(types = { TestParameterGroup.class }, column = "test_parameter_group_fk", dependent = "true")
private Map<String, TestParameterGroup> parameterGroups;

这些是TestParameterGroup字段

@Persistent(primaryKey = "true", valueStrategy = IdGeneratorStrategy.IDENTITY)
private long id;
private String name;
private String key;
private boolean active;
@Column(name = "script_substitute")
private boolean scriptSubstitute;
@Column(name = "substitute_all")
private boolean substituteAll;
@Column(name = "script_value_when_checked")
private String scriptValueWhenChecked;
@Column(name = "script_value_when_unchecked")
private String scriptValueWhenUnChecked;
@Persistent(defaultFetchGroup = "true")
@Key(types = { String.class }, mappedBy = "key", dependent = "true")
@Value(types = { TestParameter.class }, column = "parameters_group_id", dependent = "true")
private Map<String, TestParameter> parameters;

这些是TestParameter字段

@Persistent(primaryKey = "true", valueStrategy = IdGeneratorStrategy.IDENTITY)
private long id;
private String key;
private String value;
private boolean active;
@Column(name = "script_substitute")
private boolean scriptSubstitute;
@Column(name = "substitute_all")
private boolean substituteAll;

我仍在构建我的查询，但为了确保没有任何问题，我尝试在完成整个查询之前运行它，但我得到了这个异常：

为什么 DN 认为我需要任何基于地理的课程？

查询很奇怪（恕我直言）。你有

parameterGroups.get(oGroup.key).contains(tp)

然而“parameterGroups”是一个地图，所以“parameterGroups.get(...)”是一个TestParameterGroup。因此，“TestParameterGroup.contains”试图做什么。或者“oGroup.contains(...)”也为此。

如果您将该类抛出异常，那么您可以引用它，或者在类路径中包含各种随机 jar，例如“datanucleus-spatial”。
