Create a Document from a JavaBean

Sample JavaBean Class

Suppose that you are using a JavaBean class named ExampleJson:

package com.example;
        
import java.util.ArrayList;
import java.util.HashMap;
import java.util.List;
import java.util.Map;
import javax.annotation.Generated;
import com.fasterxml.jackson.annotation.JsonAnyGetter;
import com.fasterxml.jackson.annotation.JsonAnySetter;
import com.fasterxml.jackson.annotation.JsonIgnore;
import com.fasterxml.jackson.annotation.JsonInclude;
import com.fasterxml.jackson.annotation.JsonProperty;
import com.fasterxml.jackson.annotation.JsonPropertyOrder;
        
@JsonInclude(JsonInclude.Include.NON_NULL)
@Generated("org.jsonschema2pojo")
@JsonPropertyOrder({
    "a",
    "b",
    "array"
})

public class ExampleJson {
        
    @JsonProperty("a")
    private Double a;
    @JsonProperty("b")
    private String b;
    @JsonProperty("array")
    private List<Object> array = new ArrayList<Double>();
    @JsonIgnore
    private Map<String, Object> additionalProperties = new HashMap<String, Object>();
        
    /**
      *
      * @return
      * The a
      */
    @JsonProperty("a")    
    public Double getA() {
        return a;
    }
        
    /**
      *
      * @param a
      * The a
      */
    @JsonProperty("a")
    public void setA(Double a) {
        this.a = a;
    }
        
    /**
      *
      * @return
      * The b
      */
    @JsonProperty("b")
    public String getB() {
        return b;
    }
        
    /**
      *
      * @param b
      * The b
      */
    @JsonProperty("b")
    public void setB(String b) {
        this.b = b;
    }
        
    /**
      *
      * @return
      * The array
      */
    @JsonProperty("array")
    public List<Object> getArray() {
        return array;
    }
        
    /**
      *
      * @param array
      * The array
      */
    @JsonProperty("array")
    public void setArray(List<Object> array) {
        this.array = array;
    }
        
    @JsonAnyGetter
    public Map<String, Object> getAdditionalProperties() {
        return this.additionalProperties;
    }
        
    @JsonAnySetter
    public void setAdditionalProperty(String name, Object value) {
        this.additionalProperties.put(name, value);
    }
}

Create a Bean

You can create a bean for the ExampleJson class with the following code:

ExampleJson bean = new ExampleJson();
        
bean.setA(1);
bean.setB("aString");
        
List arrList = new ArrayList();
arrList.add(1);
arrList.add(2);
arrList.add("arrStr");
        
Map arrMap = new HashMap();
arrMap.put("c","arrMapStr");
arrList.add(arrMap);
bean.setArray(arrList);    

Create a New Document from a Bean

After creating the ExampleJson bean, you can create a JSON document using the bean with the following call:

Document pojoDoc = connection.newDocument(bean);    

The document will have the following structure:

{
    "a":1,
    "b":"aString",
    "array":[  
        1,
        2,
        "arrStr",
        {  
            "c":"arrMapStr"
        }
    ]
}

Create a JavaBean from a JSON Document

You can also create a JavaBean from a JSON document. For example, suppose you modify the document that you created earlier:

pojoDoc.set("d","10");

The following converts the modified document back into an ExampleJson bean:

ExampleJson bean = pojoDoc.toJavaBean(ExampleJson.class);
