You can add this template to Eclipse by open its preferences and go to Java -> Editor -> Templates. Click New... on the right side and enter the following:

• Name: dataProvider
• Context: Java type members
• Automatically insert: false
• Description: Insert a junit dataprovider method
• Use code formatter: false (unfortunately, this is a global setting for all templates)
• Pattern:

@${dataProviderType:newType(com.tngtech.java.junit.dataprovider.DataProvider)}
public static Object[][] dataProvider${Name}() {
    // @formatter:off
    return new Object[][] {
        { ${cursor} },
    };
    // @formatter:on
}
