Maven Plugin For JSON Files

[Gautam Singh]

Hi, 

I'm trying to use jsonschema2pojo to generate POJO files from JSON Files and the plugin is not working for me. I'm able to create POJOs from JSON Schema Files but not from JSON Files. 

I'm using the following pom.xml configuration 

<plugins>

                <plugin>

                    <groupId>org.jsonschema2pojo</groupId>

                    <artifactId>jsonschema2pojo-maven-plugin</artifactId>

                    <version>0.4.2</version>

                    <configuration>

                        <sourceDirectory>${basedir}/src/main/resources/schema2</sourceDirectory>

                        <outputDirectory>${basedir}/src/main/java</outputDirectory>

                        <targetPackage>pojos</targetPackage>

                    </configuration>

                    <executions>

                        <execution>

                            <goals>

                                <goal>generate</goal>

                            </goals>

                        </execution>

                    </executions>

                </plugin>

                <plugin>

                    <groupId>org.apache.maven.plugins</groupId>

                    <artifactId>maven-compiler-plugin</artifactId>

                    <version>3.1</version>

                    <configuration>

                        <source>1.6</source>

                        <target>1.6</target>

                    </configuration>

                </plugin>

                    <plugin>

                        <artifactId>maven-compiler-plugin</artifactId>

                        <version>2.3.2</version>

                    </plugin>

                   </plugins>

Is it possible to use JSON files to generate the POJOs ? Any help would be highly appreciated. 

Thanks, 

G.

Hi Gautam

To use JSON as your input instead of JSON Schema, you simply need to add this to your plugin configuration:

<sourceType>json</sourceType>

Cheers

Hi, 

How can I generate the pojo classes in different packages with the json files in different folders? For example, I want to generate the the java objects for request and response in different packages with the json files stores in request/ and response/ folder separately. 

Thanks a lot,

Lisa

I'd recommend that you either:

1. Invoke the plugin more than once or

2. Point the plugin at the parent directory (it works recursively) and use javaType to make sure your classes have the right FQCN

What have you checked out so far, what approaches tried? What failed?
Or is this is the case of "do my homework"? It is customary to do due diligence first.

Hi,

      I tried to create the pojos from JSON(not JSONSchema) using maven plugin. I am able to create pojos. But there is a problem like 

   JSONs:

   =========

  {

"name" : "sandeep",

"id" : 12,

"address" : {

"add1" : "ab",

"add2" : "cd",

"state" : "up",

"country" : "India"

}

  }

 {

"name" : "rajesh",

"id" : 13,

"address" : {

"add1" : "xy",

"state" : "ap"

}

 }

 classes:

 ========

  public class Address{

  private String add1;

  private String add2;

  private String state;

  private String country;

 //setters and getters

 }

  public class Address__ {

  private String add1;

  private String state;

  }


        How could I generate only one class(Address) include all the properties in all Jsons(merge all the updates for the same class generated first time).

Try to add one property <configuration><sourceType>json</sourceType></configuration>.

It will generate the pojos from Json.

Your best option is to give jsonschema2pojo *one* json file that contains a superset of fields for Address. You could create this by merging your Json files before giving them to this plugin.

Previously I generated pojos through Ant using swagger at that time I didn't get any problem. But while trying to create those pojos from same JSON file I am getting duplicate classes contains additional properties in the new class by adding "___" for class names. There is no way to avoid this means clubbing at the runtime(classes) by maven.
