如何使用Jackson将JSON字符串解析为数组
问题描述：
我有字符串，其值如下：
[{"key1":"value11", "key2":"value12"},{"key1":"value21", "key2":"value22"}]
以下类：
public class SomeClass {
private String key1;
private String key2;
/* ... getters and setters omitted ...*/
}
列表< SomeClass> 或 SomeClass []
使用 Jackson 这是最简单的方法 ObjectMapper ？
Which is the simplest way to do it using Jackson ObjectMapper?
答
我终于明白了：
ObjectMapper objectMapper = new ObjectMapper();
TypeFactory typeFactory = objectMapper.getTypeFactory();
List<SomeClass> someClassList = objectMapper.readValue(jsonString, typeFactory.constructCollectionType(List.class, SomeClass.class));
