java.lang.NoSuchMethodError：org.json.JSONObject。<init>（Ljava / lang / Object;）V

Question

我有一个基本的SpringBoot 2.1.5.RELEASE应用程序。使用Spring Initializer，JPA，嵌入式Tomcat，Thymeleaf模板引擎，并将其打包为带有一些RestController的可执行JAR文件。

在控制器1中，这是我发送的正文：

{
    "depositHotel": "xxx",
    "destinationHotel": "aaa",
    "depositHotelAmount": "0.2",
    "destinationHotelAmount": "4",
    "destinationAddress": [{
        "address": "asdf",
        "tag": ""
    }],
    "refundAddress": [{
        "address": "pio",
        "tag": ""
    }]
}

所以我创建了该类以将其作为RequestBody发送：

@JsonInclude(JsonInclude.Include.NON_NULL)
@JsonPropertyOrder({
"address",
"tag"
})
public class Address {



    public Address() {
        super();
    }

    public Address(String address) {
        super();
        this.address = address;
    }

    @JsonProperty("address")
    private String address;
    @JsonProperty("tag")
    private Object tag;


    @JsonProperty("address")
    public String getAddress() {
    return address;
    }

    @JsonProperty("address")
    public void setAddress(String address) {
    this.address = address;
    }

    @JsonProperty("tag")
    public Object getTag() {
    return tag;
    }

    @JsonProperty("tag")
    public void setTag(Object tag) {
    this.tag = tag;
    }
}

Answer 1

看起来您的类路径上有多个org.json：json依赖项。

看着它：

org.springframework.boot:spring-boot-starter-test取决于

com.jayway.jsonpath:json-pathwhich依次带来

org.json:json可能比其版本新/旧

io.jsonwebtoken jjwt 0.9.1是依赖对象

您可以尝试从spring-boot-starter-test / io.jsonwebtoken中排除此传递依赖项：

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-test</artifactId>
    <scope>test</scope>
    <exclusions>
        <exclusion>
            <groupId>org.json</groupId>
            <artifactId>json</artifactId>
        </exclusion>
    </exclusions>
</dependency>

OR / AND

<dependency>
    <groupId>io.jsonwebtoken</groupId>
    <artifactId>jjwt</artifactId>
    <version>0.9.1</version>
    <exclusions>
        <exclusion>
            <groupId>org.json</groupId>
            <artifactId>json</artifactId>
        </exclusion>
    </exclusions>
</dependency>

但是json-path中可能有某些内容依赖于旧json库中的内容，而新版本中已不再存在，因此请谨慎操作并彻底测试所有内容。 也有可能其他东西带来了org.json：json。

要进行验证，请运行mvn dependency:tree并在产生的输出中搜索org.json:json。

Answer 2

您的destinationAddress和refundAddress在JSON中作为地址或地址数组的列表传递，而在HotelswitchHotelOrderRequestBody中，您的destinationAddress和refundAddress被引用作为单个地址元素。更新您的pojo或JSON，然后重试。这可能是个问题。

Answer 3

您需要使用ObjectMapper将POJO转换为JSONObject或包含json dependency

<dependency>
    <groupId>org.json</groupId>
    <artifactId>json</artifactId>
    <version>20180130</version>
</dependency>

Answer 4

问题应该出在您的JSON和POJO之间的destinationAddress和退款地址不匹配。 尝试像这样更改您的JSON：

{ "depositHotel": "xxx", "destinationHotel": "aaa", "depositHotelAmount": "0.2", "destinationHotelAmount": "4", "destinationAddress": { "address": "asdf", "tag": "" }, "refundAddress": { "address": "pio", "tag": "" } }

如果您不想更改JSON，请将Builder POJO更改为使用Address []而不是Address对象。

Answer 5

您不需要JSONobject

HttpEntity<HotelswitchHotelOrderRequestBody> entity = new HttpEntity<HotelswitchHotelOrderRequestBody>(order, headers());

如果您要做的只是将对象转换为字符串，请使用对象映射器。

ObjectMapper objectMapper = new ObjectMapper();
String json = objectMapper.writeValueAsString(car)

Answer 6

我在另一页上找到了这个。我在这里尝试了已检查的答案，但它与我的不兼容，但是当我将其插入到pom文件中时，它可以正常工作。我正在使用Mockito运行单元测试，并且端点之一使用JSONObject.put并没有出现此类错误。

<dependency>
        <groupId>
            org.springframework.boot
        </groupId>
        <artifactId>
            spring-boot-starter-test
        </artifactId>
        <scope>test</scope>
        <exclusions>
            <exclusion>
                <groupId>org.json</groupId>
                <artifactId>json</artifactId>
            </exclusion>
            <exclusion>
                <groupId>com.vaadin.external.google</groupId>
                <artifactId>android-json</artifactId>
            </exclusion>
        </exclusions>
    </dependency>

Answer 7

请检查此链接： spring-boot issue 8706

从spring-boot-starter-test中排除android-json对我有用。

 <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-test</artifactId>
        <scope>test</scope>
        <exclusions>
            <exclusion>
                <groupId>com.vaadin.external.google</groupId>
                <artifactId>android-json</artifactId>
            </exclusion>
        </exclusions>
    </dependency>
