解析 list-json

orderlist.json

[  {    "item": "No. 9 Sprockets",    "quantity": 12,    "unitPrice": 1.23,    "orderDate": "2019-04-17"  },  {    "item": "No. Widget (10mm)",    "quantity": 10,    "unitPrice": 3.45,    "orderDate": "2022-01-16"  }]

List 类型解析

直接声明类型{style=width:500px}

@Testvoid orderListMap() throws IOException {    ObjectMapper mapper = new ObjectMapper(new JsonFactory());    TypeReference<List<HashMap<String, Object>>> typeReference =            new TypeReference<List<HashMap<String, Object>>>() {};    mapper.findAndRegisterModules();    List<HashMap<String, Object>> listHashMap =            mapper.readValue(                    new File("src/test/resources/json/orderlist.json"),                    typeReference);
    System.out.println(listHashMap.toString());}

复制代码

实体类声明

声明实体类 OrderLine

@Datapublic class OrderLine{    private String item;    private int quantity;    private BigDecimal unitPrice;    private LocalDate orderDate;
    public OrderLine() {    }
    public OrderLine(String item, int quantity,     BigDecimal unitPrice, LocalDate orderDate) {        this.item = item;        this.quantity = quantity;        this.unitPrice = unitPrice;        this.orderDate = orderDate;    }}

实体类对应解析

@Testvoid orderLinesTest() throws IOException {    ObjectMapper mapper = new ObjectMapper(new JsonFactory());    TypeReference<List<OrderLine>> typeReference =            new TypeReference<List<OrderLine>>() {};    mapper.findAndRegisterModules();    List<OrderLine> orderLines =            mapper.readValue(                    new File("src/test/resources/json/orderlist.json"),                    typeReference);
    System.out.println(orderLines);}

解析无规律 json

order.json

{  "orderNo": "A001",  "date": "2019-04-17",  "customerName": "Customer, Joe",  "orderLines": [    {      "item": "No. 9 Sprockets",      "quantity": 12,      "unitPrice": 1.23    },    {      "item": "No. Widget (10mm)",      "quantity": 40,      "unitPrice": 3.45    }  ]}

@Datapublic class Order {    private String orderNo;    private LocalDate date;    private String customerName;    private List<OrderLine> orderLines;

    public Order() {    }
    public Order(String orderNo, LocalDate date,     String customerName, List<OrderLine> orderLines) {        this.orderNo = orderNo;        this.date = date;        this.customerName = customerName;        this.orderLines = orderLines;    }}
