我正在从代码中的信息创建两个不同的数组。我需要将这两个连接(合并)为一个并生成一个json对象以传递给另一个方法。我更喜欢使用gson,因为我正在使用那些
我正在使用gson,尝试了很多不同的方法,我完全迷失了。有什么帮助吗?
注意:我已尝试将mList添加到asMap,
asMap.putAll(mList);
但是
putAll (java.util.Map<? extends java.lang.String,? extends java.lang.string>) in Map cannot be applied to (java.util.List <java.util.Map<java.lang.String,java.lang.String>>)
我有一个数组:
Map<String, String> asMap = new HashMap<>();
看起来像:
{
"batchId":"25248e931e5948b990f528d26ee6a9f5",
"almServer":"server.com",
"almDomain":"EBUSINESS",
"almProject":"STERLING",
"testSetUrl":"http://test.com",
"testParameters":"{\"browser\":\"chrome\",\"browser-version\":\"56\",\"language\":\"english\",\"country\":\"USA\"}",
"startTime":"01/20/2018 06:37:05 PM",
"finishTime":"01/21/2018 05:30:25 AM",
"totalDuration":"10h 53m 19s 922ms",
"passed":159,
"testsExecuted":214,
"failed":52,
"notCompleted":3,
"testPassPercentage":"75.4"
}
第二个:
List<Map<String, String>> mList = new ArrayList<Map<String, String>>();
看起来像:
[
{
"runDuration":"9m 33s 642ms",
"testId":"12100",
"automatedTest":"CancelFullOrder",
"batchItemPosition":"1",
"runPosition":"1",
"executionDate":"01/21/2018",
"executionTime":"02:48:50 AM",
"runId":"69257",
"status":"PASSED"
},
{
"runDuration":"8m 56s 991ms",
"testId":"12101",
"automatedTest":"CancelOrderPartially",
"batchItemPosition":"2",
"runPosition":"1",
"executionDate":"01/21/2018",
"executionTime":"02:49:30 AM",
"runId":"69258",
"status":"PASSED"
}
]
我想将它们组合成一个看起来像的jsonobject:
{
"batchId":"25248e931e5948b990f528d26ee6a9f5",
"almServer":"server.com",
"almDomain":"EBUSINESS",
"almProject":"STERLING",
"testSetUrl":"http://test.com",
"testParameters":"{\"browser\":\"chrome\",\"browser-version\":\"56\",\"language\":\"english\",\"country\":\"USA\"}",
"executedTests":[
{
"runDuration":"9m 33s 642ms",
"testId":"12100",
"automatedTest":"CancelFullOrder",
"batchItemPosition":"1",
"runPosition":"1",
"executionDate":"01/21/2018",
"executionTime":"02:48:50 AM",
"runId":"69257",
"status":"PASSED"
},
{
"runDuration":"8m 56s 991ms",
"testId":"12101",
"automatedTest":"CancelOrderPartially",
"batchItemPosition":"2",
"runPosition":"1",
"executionDate":"01/21/2018",
"executionTime":"02:49:30 AM",
"runId":"69258",
"status":"PASSED"
}
],
"startTime":"01/20/2018 06:37:05 PM",
"finishTime":"01/21/2018 05:30:25 AM",
"totalDuration":"10h 53m 19s 922ms",
"passed":159,
"testsExecuted":214,
"failed":52,
"notCompleted":3,
"testPassPercentage":"75.4"
}

从您的问题和您对评论中的问题的回答中可以看出,您自己正在构建这些结构,并且可以更改它们的定义。正如评论中指出的那样,问题在于您的顶级结构(即HashMap)具有String类型的值。由于您要将List作为值添加,因此必须将HashMap值的类型概括为Object:
Map<String, Object> asMap = new HashMap<>();
如果您自己构建HashMap,则在构建Map时应该能够使用这个新定义。但是,如果您已经拥有Map<String, String>
,则可以使用:
Map<String, Object>
@SuppressWarnings("unchecked")
Map<String, Object> topMap = (Map<String, Object>) (Map<String, ?>) asMap;
(也许有一种更好的方法可以做到这一点.Java不能假设,因为String是Object的子类,它可以做这个演员。为什么它需要两个演员才能使这项工作超出我的理解。)
然后,将它们组合起来:
asMap.put("executedTests", mList);
如果你使用上面的演员表,请用{{1>}代替topMap
。
