为了生成只读的接口和xml，并命名结尾为MapperR.java和MapperR.xml

《一》首先从https://github.com/mybatis/generator下载源代码，然后找到org.mybatis.generator.api下面的IntrospectedTable文件，修改以下两个方法，然后重新打个jar包。

1.修改calculateJavaClientAttributes方法

protected void calculateJavaClientAttributes() {
        if (context.getJavaClientGeneratorConfiguration() == null) {
            return;
        }

        StringBuilder sb = new StringBuilder();
        sb.append(calculateJavaClientImplementationPackage());
        sb.append('.');
        sb.append(fullyQualifiedTable.getDomainObjectName());
        sb.append("DAOImpl"); //$NON-NLS-1$
        setDAOImplementationType(sb.toString());

        sb.setLength(0);
        sb.append(calculateJavaClientInterfacePackage());
        sb.append('.');
        sb.append(fullyQualifiedTable.getDomainObjectName());
        sb.append("DAO"); //$NON-NLS-1$
        setDAOInterfaceType(sb.toString());

        sb.setLength(0);
        sb.append(calculateJavaClientInterfacePackage());
        sb.append('.');
        sb.append(fullyQualifiedTable.getDomainObjectName());
        sb.append("Mapper"); //$NON-NLS-1$
        
        if(null!=calculateJavaClientInterfacePackage() && calculateJavaClientInterfacePackage().endsWith(".dro")){
        	setMyBatis3JavaMapperType(sb.toString()+"R");
        }else{
        	setMyBatis3JavaMapperType(sb.toString());
        }

        sb.setLength(0);
        sb.append(calculateJavaClientInterfacePackage());
        sb.append('.');
        sb.append(fullyQualifiedTable.getDomainObjectName());
        sb.append("sqlProvider"); //$NON-NLS-1$
        setMyBatis3sqlProviderType(sb.toString());
    }

2.修改calculateMyBatis3XmlMapperFileName方法

protected String calculateMyBatis3XmlMapperFileName() {
        StringBuilder sb = new StringBuilder();
        sb.append(fullyQualifiedTable.getDomainObjectName());
      
        if(null!=calculateJavaClientInterfacePackage() && calculateJavaClientInterfacePackage().endsWith(".dro")){
        	 sb.append("MapperR.xml"); //$NON-NLS-1$
        }else{
        	 sb.append("Mapper.xml"); //$NON-NLS-1$
        }
        
        return sb.toString();
    }

《二》generatorConfiguration的配置文件，javaClientGenerator的targetPackage这个包的名字需要以 ".dro" 结尾

《三》使用命令

java -jar mybatis-generator-core-1.3.2.jar -configfile generatorConfig-dro.xml -overwrite

即可生成只读的接口和xml了，并命名结尾为MapperR.java和MapperR.xml。
