This spring example is using xml base config
But it creates object using explict new operator.

public class Brand { private Long id; private String name; private String country;
public String getCountry() { return country; } public void setCountry(String country) { this.country = country; } public Long getId() { return id; } public void setId(Long id) { this.id = id; } public String getName() { return name; } public void setName(String name) { this.name = name; } }

public class Car { private Long id; private Brand brand; private String model; private BigDecimal price;
public Long getId() { return id; } public void setId(Long id) { this.id = id; } public Brand getBrand() { return brand; } public void setBrand(Brand brand) { this.brand = brand; } public String getModel() { return model; } public void setModel(String model) { this.model = model; } public BigDecimal getPrice() { return price; } public void setPrice(BigDecimal price) { this.price = price; } }
