SSM+vue基础项目从零开始练习后端搭建
创建后端项目
1、搭建maven工程
直接把项目建立在仓库的根目录即可，当然我们也可以创建两个仓库，一个前端项目仓库，一个后端项目仓库：
删除父工程下的src
调整工程结构
2、调整工程结构
创建子工程 system-adimin，删除掉父工程的src，将父工程的pom文件中的packaging改为pom，声明为一个父工程：
3、配置tomcat
4、加入以下依赖
在父工程中加入以下依赖，进行依赖管理，每一个依赖的作用不在赘述，这是基本的ssm项目搭建

logback日志的配置文件 logback.xml：

${log.path}/sys-info.%d{yyyy-MM-dd}.log

${log.pattern}

ACCEPT
DENY
${log.path}/sys-error.log
${log.path}/sys-error.%d{yyyy-MM-dd}.log

${log.pattern}

创建CustomObjectMapper来配置jackson的序列化和反序列化：
public class CustomObjectMapper extends ObjectMapper {
public CustomObjectMapper() {
super();
//去掉默认的时间戳格式
configure(SerializationFeature.WRITE_DATES_AS_TIMESTAMPS, false);
//设置为东八区
setTimeZone(TimeZone.getTimeZone("GMT+8"));
//设置日期转换yyyy-MM-dd HH:mm:ss
setDateFormat(new SimpleDateFormat("yyyy-MM-dd HH:mm:ss"));
// 设置输入:禁止把POJO中值为null的字段映射到json字符串中
configure(SerializationFeature.WRITE_NULL_MAP_VALUES, false);
// 空值不序列化
setSerializationInclusion(JsonInclude.Include.NON_NULL);
// 反序列化时，属性不存在的兼容处理
getDeserializationConfig().withoutFeatures(DeserializationFeature.FAIL_ON_UNKNOWN_PROPERTIES);
// 序列化枚举是以toString()来输出，默认false，即默认以name()来输出
configure(SerializationFeature.WRITE_ENUMS_USING_TO_STRING, true);
}
}5、构建目录结构并测试：
启动测试
http://localhost:8080/admin/
http://localhost:8080/admin/test
如遇无法启动更换端口尝试
测试controller
@Controller
public class TestController {
@GetMapping("user")
@ResponseBody
public User test(){
return new User("tom",12);
}
@ResponseBody
public User test(){
return new User("tom",12);
}
static class User{
String username;
Integer age;
public User(String username, Integer age) {
this.username = username;
this.age = age;
}
public String getUsername() {
return username;
}
public void setUsername(String username) {
this.username = username;
}
public Integer getAge() {
return age;
}
public void setAge(Integer age) {
this.age = age;
}
}
}启动成功
访问
http://localhost:8080/admin/user
