# mapstruct-support

Additional DefaultAccessorNamingStrategy to support fluent API withXYZ setters.

Mapstruct default naming strategy detects the methods `withFirstName` and `withLastName` (see example below) as extra
target fields are therefore cause an error, when the mapper is annotated with
`unmappedTargetPolicy = ReportingPolicy.ERROR`.

## Installation

To use the extended naming strategy, just include it as project dependency alongside with mapstruct.

```xml

<dependencies>
  <dependency>
    <groupId>org.mapstruct</groupId>
    <artifactId>mapstruct</artifactId>
    <version>1.4.2.Final</version>
  </dependency>
  <dependency>
    <groupId>de.muehlencord.mapstruct</groupId>
    <artifactId>mapstruct-support</artifactId>
    <version>1.4.2</version>
  </dependency>
</dependencies>
```

## Example

```java
public class Person {

  private String firstName;
  private String lastName;

  // standard getter / setter - these are covered by mapstruct by default */
  public String getFirstName() {
    return firstName;
  }

  public void setFirstName(String firstName) {
    this.firstName = firstName;
  }

  public String getLastName() {
    return lastName;
  }

  public void setLastName(String lastName) {
    this.lastName = lastName;
  }

  /* fluent setter - these are detected as extra setters and would
     cause an mapping exception, if the mapper is annotated with 
     unmappedTargetPolicy = ReportingPolicy.ERROR. 
   */

  public Person withFirstName(String firstName) {
    this.firstName = firstName;
    return this;
  }

  public Person withLastName(String lastName) {
    this.lastName = lastName;
    return this;
  }
}

```
