| = Testing Security |
| |
| Este é um simples exemplo que demonstra como utilizar as anotações de segurança para conseguir configurar nível de acessos a métodos em `DAO`. Ao final, demonstramos através de um teste de unidade qual é o comportamento resultante da restrição de acesso a determinada ação. |
| |
| == Filme |
| |
| Criamos uma classe de entidade com informações de filme. |
| |
| [source,java] |
| ---- |
| package org.superbiz.injection.secure; |
| |
| import javax.persistence.Entity; |
| |
| @Entity |
| public class Movie { |
| |
| private String director; |
| private String title; |
| private int year; |
| |
| public Movie() { |
| } |
| |
| public Movie(String director, String title, int year) { |
| this.director = director; |
| this.title = title; |
| this.year = year; |
| } |
| |
| public String getDirector() { |
| return director; |
| } |
| |
| public void setDirector(String director) { |
| this.director = director; |
| } |
| |
| public String getTitle() { |
| return title; |
| } |
| |
| public void setTitle(String title) { |
| this.title = title; |
| } |
| |
| public int getYear() { |
| return year; |
| } |
| |
| public void setYear(int year) { |
| this.year = year; |
| } |
| |
| } |
| ---- |
| |
| == Filmes |
| |
| Criamos outra classe DAO para Filme. Observe que utilizamos as anotações para dizer as roles necessárias para utilização de cada ação disponível. Por exemplo, adicionar um filme é possível para um usuário que tenha a `ROLE` "Manager" ou "Employee", mas a remoção de um filme pode ser feita somente por quem tem a `ROLE` Manager. |
