# How it works
\nKnowledge Book uses https:\/\/mongojack.org\/ as its main api to help convert java classes to mongo documents. All Knowledge Book does is allow developers to seamlessly integrate this into your plugins.<\/p>\n
### As an example, you can convert a Java Class into a MongoDB document.
\n“`java
\npackage gg.lode.example.data;<\/p>\n
import com.fasterxml.jackson.annotation.JsonProperty;
\nimport to.lodestone.knowledgebook.annotation.Collection;<\/p>\n
@Collection(name = “person_collection”)
\npublic class Person {<\/p>\n
@JsonProperty(“fullName”)
\n private String fullName;<\/p>\n
@JsonProperty(“socialSecurityNumber”)
\n private String socialSecurityNumber;<\/p>\n
\/\/ For Knowledge Book to initialize an empty object to use getters and setters.
\n public Person() {<\/p>\n
}<\/p>\n
public Person(String fullName, String socialSecurityNumber) {
\n this.fullName = fullName;
\n this.socialSecurityNumber = socialSecurityNumber;
\n }<\/p>\n
@JsonProperty(“fullName”)
\n public void setFullName(String fullName) {
\n this.fullName = fullName;
\n }<\/p>\n
@JsonProperty(“fullName”)
\n public String getFullName() {
\n return fullName;
\n }<\/p>\n
@JsonProperty(“socialSecurityNumber”)
\n public void setSocialSecurityNumber(String socialSecurityNumber) {
\n this.socialSecurityNumber = socialSecurityNumber;
\n }<\/p>\n
@JsonProperty(“socialSecurityNumber”)
\n public String getSocialSecurityNumber() {
\n return socialSecurityNumber;
\n }
\n}
\n“`<\/p>\n
### How to use Knowledge Book in your plugin:
\n“`java
\npackage to.lodestone.example;<\/p>\n
import org.bukkit.plugin.java.JavaPlugin;
\nimport org.mongojack.JacksonMongoCollection;
\nimport gg.lode.example.data.Person;

\nimport to.lodestone.knowledgebook.KnowledgeBookAPI;<\/p>\n
public class TestPlugin extends JavaPlugin {<\/p>\n
@Override public IKnowledgeBookAPI knowledgeBook() { ### Once you’ve started up your server, it will create a collection called `person_collection` with a new Person document with all of the data you’ve provided. ### Remember to set your variables with the correct values in order for Knowledge Book to properly function within the “config.yml” file!
