自动生成Mapper代码

public class BeanMapperTest {
    @Test
    public void build() throws Exception {
        Class clazz = RiskAccess.class;//把  RiskAccess替换成自己对应的model即可
        System.out.println("public final static RowMapper<#ClassName> #ClassName_MAPPER = (rs, rowNum) -> {".replace("#ClassName", clazz.getSimpleName()));
        System.out.println("#ClassName dto = new #ClassName();".replace("#ClassName", clazz.getSimpleName()));
        for (java.lang.reflect.Method method : clazz.getMethods()) {
            String methodName = method.getName();
            String fieldName = methodName.replace("set", "");
            if (methodName.contains("set")) {
                Class paramType = method.getParameters()[0].getType();
                System.out.println("dto.#MethodName(rs.get#ParamType("#FieldName"));"
                        .replace("#MethodName", methodName)
                        .replace("#ParamType", paramType.getSimpleName())
                        .replace("#FieldName", fieldName));
            }
        }
        System.out.println("return dto;");
        System.out.println("};");
    }
}

 注意：如果表的字段名称有下划线，而对应POJO的字段没有下划线，则需要手动加上下划线，并且mapper只支持getInt()方法 ，而不支持getInteger()方法
