package org.model;

import javax.xml.bind.annotation.XmlAccessType;
import javax.xml.bind.annotation.XmlAccessorType;
import javax.xml.bind.annotation.XmlAttribute;
import javax.xml.bind.annotation.XmlRootElement;

@XmlRootElement(name = "param")
@XmlAccessorType(XmlAccessType.NONE)
public class Param {

    @XmlAttribute(name = "name")
    private String name;

    @XmlAttribute(name = "type")
    private String type;

    @XmlAttribute(name = "pattern")
    private String pattern;

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public String getType() {
        return type;
    }

    public void setType(String type) {
        this.type = type;
    }

    public String getPattern() {
        return pattern;
    }

    public void setPattern(String pattern) {
        this.pattern = pattern;
    }

    @Override
    public String toString() {
        final StringBuilder sb = new StringBuilder("Param{");
        sb.append("name='").append(name).append('\'');
        sb.append(", type='").append(type).append('\'');
        sb.append(", pattern='").append(pattern).append('\'');
        sb.append('}');
        return sb.toString();
    }
}

package org.model;

import javax.xml.bind.annotation.*;
import java.util.List;

@XmlRootElement(name = "rule")
@XmlAccessorType(XmlAccessType.NONE)
public class Rule {
    @XmlAttribute(name = "name")
    private String name;

    @XmlElementWrapper(name = "params")
    @XmlElement(name = "item")
    private List params;

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public List getParams() {
        return params;
    }

    public void setParams(List params) {
        this.params = params;
    }

    @Override
    public String toString() {
        final StringBuilder sb = new StringBuilder("Rule{");
        sb.append("name='").append(name).append('\'');
        sb.append(", params=").append(params);
        sb.append('}');
        return sb.toString();
    }
