在反序列化时，有两种方法可以忽略该属性
1.使用只读
只需向不想反序列化的属性添加一个注解

@JsonProperty(access = Access.READ_ONLY)
private String readOnly;

1.使用@JsonIgnore和@JsonProperty
这个方法应该小心，你应该把@JsonIgnore放在setter之前，把@JsonProperty放在getter之前，并且对于这个属性应该清除，不带任何注解。

@JsonProperty
public String getJsonIgnoreSetter() {
    return jsonIgnoreSetter;
}

@JsonIgnore
public void setJsonIgnoreSetter(String jsonIgnoreSetter) {
    this.jsonIgnoreSetter = jsonIgnoreSetter;
}

最后，给出了@JsonIgnore、@JsonProperty、@JsonProperty（access = xxx）的完整注解示例。
bean的定义

public class MockBean{

    public MockBean() {
        super(MockBean.class);
    }

    public MockBean(String attr1, String ignore, String jsonIgnore, String jsonIgnoreGetter,
            String jsonIgnoreSetter, String jsonIgnoreProperties, String jsonIgnorePropertiesSetter,
            String jsonIgnorePropertiesGetter, String readOnly, String writeOnly) {
        super(MockBean.class);
        this.attr1 = attr1;
        this.ignore = ignore;
        this.jsonIgnore = jsonIgnore;
        this.jsonIgnoreGetter = jsonIgnoreGetter;

        this.jsonIgnorePropertiesSetter = jsonIgnorePropertiesSetter;
        this.jsonIgnorePropertiesGetter = jsonIgnorePropertiesGetter;
        this.readOnly = readOnly;
        this.writeOnly = writeOnly;
    }

    public String getAttr1() {
        return attr1;
    }

    public void setAttr1(String name) {
        this.attr1 = name;
    }

    public String getIgnore() {
        return ignore;
    }

    public void setIgnore(String ignore) {
        this.ignore = ignore;
    }

    public String getJsonIgnore() {

    public void setJsonIgnore(String jsonIgnore) {
        this.jsonIgnore = jsonIgnore;
    }

    @JsonIgnore
    public String getJsonIgnoreGetter() {

    }

    @JsonProperty
    public void setJsonIgnoreGetter(String jsonIgnoreGetter) {
        this.jsonIgnoreGetter = jsonIgnoreGetter;
    }

    @JsonProperty
    public String getJsonIgnoreSetter() {
        return jsonIgnoreSetter;

    @JsonIgnore
    public void setJsonIgnoreSetter(String jsonIgnoreSetter) {

    }

    public String getJsonIgnoreProperties() {

    }

    public void setJsonIgnoreProperties(String jsonIgnoreProperties) {
        this.jsonIgnoreProperties = jsonIgnoreProperties;
    }

    public String getJsonIgnorePropertiesSetter() {
        return jsonIgnorePropertiesSetter;
    }

    @JsonIgnoreProperties
    public void setJsonIgnorePropertiesSetter(String jsonIgnorePropertiesSetter) {
        this.jsonIgnorePropertiesSetter = jsonIgnorePropertiesSetter;
    }

    @JsonIgnoreProperties
    public String getJsonIgnorePropertiesGetter() {
        return jsonIgnorePropertiesGetter;
    }

    public void setJsonIgnorePropertiesGetter(String jsonIgnorePropertiesGetter) {
        this.jsonIgnorePropertiesGetter = jsonIgnorePropertiesGetter;
    }

    public String getReadOnly() {
        return readOnly;
    }

    public void setReadOnly(String readOnly) {
        this.readOnly = readOnly;
    }

    public String getWriteOnly() {
        return writeOnly;
    }

    public void setWriteOnly(String writeOnly) {
        this.writeOnly = writeOnly;
    }

    private String attr1;
    @Ignore
    private String ignore;
    @JsonIgnore
    private String jsonIgnore;
    @JsonIgnore
    private String jsonIgnoreGetter;
    @JsonIgnore
    private String jsonIgnoreSetter;
    @JsonIgnoreProperties
    private String jsonIgnoreProperties;
    private String jsonIgnorePropertiesSetter;
    private String jsonIgnorePropertiesGetter;
    @JsonProperty(access = Access.READ_ONLY)
    private String readOnly;
    @JsonProperty(access = Access.WRITE_ONLY)
    private String writeOnly;
}

测试JSON

反序列化的结果：如果该值为null，则不对该值进行反序列化。
