其实原理很简单很简单...

下面是修改后的模板代码:

#set($paramName = $helper.getParamName($field, $project))#if($field.modifierStatic)static ###end$classname set$StringUtil.capitalizeWithJavaBeanConvention($StringUtil.sanitizeJavaIdentifier($helper.getPropertyName($field, $project)))($field.type $paramName) {  #if ($field.name == $paramName)    #if (!$field.modifierStatic)      this.##    #else      $classname.##    #end  #end  $field.name = $paramName;    return this;}

自动生成的类代码:

public class User {    private String userName;    private Date createTime;    private String password;    public User() {    }    public String getUserName() {        return userName;    }    public User setUserName(String userName) {        this.userName = userName;        return this;    }    public Date getCreateTime() {        return createTime;    }    public User setCreateTime(Date createTime) {        this.createTime = createTime;        return this;    }    public String getPassword() {        return password;    }    public User setPassword(String password) {        this.password = password;        return this;    }}

实测效果,是不是很爽:

public class Test {    public static void main(String[] args) {        User tom = new User()                .setUserName("tom")                .setCreateTime(new Date())                .setPassword("123");    }}
