示例1: getMappedBy

import javax.persistence.OneToMany; //导入方法依赖的package包/类
private String getMappedBy(MetaAttribute attr) {
	ManyToMany manyManyAnnotation = attr.getAnnotation(ManyToMany.class);
	OneToMany oneManyAnnotation = attr.getAnnotation(OneToMany.class);
	OneToOne oneOneAnnotation = attr.getAnnotation(OneToOne.class);
	String mappedBy = null;
	if (manyManyAnnotation != null) {
		mappedBy = manyManyAnnotation.mappedBy();
	}
	if (oneManyAnnotation != null) {
		mappedBy = oneManyAnnotation.mappedBy();
	}
	if (oneOneAnnotation != null) {
