use of javassist.CtField in project dq-easy-cloud by dq-open-cloud.

the class DynamicRuleTest method makeclass.

public static void makeclass(String className, String methodName, String fieldName, String interfaceCode) throws NotFoundException, CannotCompileException, IOException {
    ClassPool pool = ClassPool.getDefault();
    CtClass ct = pool.makeClass("com.test.bean.Emp");
    // 创建属性
    CtField e1 = CtField.make("public int no;", ct);
    CtField e2 = CtField.make("public String name;", ct);
    ct.addField(e1);
    ct.addField(e2);
    CtMethod m1 = CtMethod.make("public int getNo(){return no;}", ct);
    CtMethod m2 = CtMethod.make("public void setNo(int no){return this.no = no;}", ct);
    ct.addMethod(m1);
    ct.addMethod(m2);
    // 添加构造器
    CtConstructor constructor = new CtConstructor(new CtClass[] { CtClass.intType, pool.get("java.lang.String") }, // 构造器的参数
    ct);
    // 构造器的方法体
    constructor.setBody("{this.no = no; this.name=name;}");
    // 如果不添加构造器 则会生成一个空的构造器
    ct.addConstructor(constructor);
    // 将构造好的类写出来
    ct.writeFile("E:/JavaFile");
    System.out.println("类生成功");
