我有 Angular 發(fā)送的 JSON 字符串：{ "transaction_id": "1234", "usage": "Test Usage", "billing_address": { "first_name": "name", "last_name": "name", "address1": "street 1234", "zip_code": "11923" }, "shipping_address": { "first_name": "name", "last_name": "name", "address1": "street 1234", "zip_code": "11923" } }Java代碼：public class DTO { private String transaction_id; private String usage; private BillingAddress billingAddress; private ShippingAddress shippingAddress; ... getter/setter}public class BillingAddress { private String firstName; private String lastName; private String address1; private String zip_code; ... getter/setter}public class ShippingAddress { private String firstName; private String lastName; private String address1; private String zip_code; ... getter/setter}彈簧端點(diǎn)：@PostMapping(value = "/{id}", consumes = { MediaType.APPLICATION_JSON_VALUE }, produces = { MediaType.APPLICATION_JSON_VALUE }) public ResponseEntity<?> handleWpfMessage(@PathVariable("id") id, @RequestBody DTO data){ ....}映射內(nèi)部對(duì)象billing_address以及shipping_address正確映射值的正確方法是什么？我是否需要添加注釋才能正確映射它們？

您應(yīng)該將以下注釋添加到 DTO 類中：
public class DTO {
private String transaction_id;
private String usage;
@JsonProperty("billing_address")
private BillingAddress billingAddress;
@JsonProperty("shipping_address")
private ShippingAddress shippingAddress;
... getter/setter
}

您的角度客戶端使用蛇盒。為了使 jackson 正確反序列化，您可以使用以下命令進(jìn)行全局配置：
spring.jackson.property-naming-strategy=SNAKE_CASE
但是您也可以為特定的類配置它：
@JsonNaming(PropertyNamingStrategy.SnakeCaseStrategy.class)
public class DTO {
}

正如已經(jīng)提到的，您可以在類中使用 Jackson 屬性映射注釋DTO。
@JsonProperty("billing_address")
private BillingAddress billingAddress;這意味著，在 json 中，屬性billing_address將被分配給billingAddress變量。
