  1. Field injection is not recommended
  3. 不建议现场主入
  5. Field injection is not recommended 
  6.  Inspection info: Spring Team recommends: 
  7. "Always use constructor based dependency injection in your beans. 
  8. Always use assertions for mandatory dependencies".
  9. 始终在bean中使用基于构造函数的依赖项注入。 始终对强制性依赖项使用断言

依赖注入有三种方式：

  1. 变量（filed）注入
  2. 构造器注入

  3. set方法注入

    @Autowired
    private SysUserPhMapper sysUserPhMapper;

    private final SysUserPhMapper sysUserPhMapper;

    1. @Autowired
    2. public SysUserServiceImpl(SysUserPhMapper sysUserPhMapper) {
    3.     this.sysUserPhMapper = sysUserPhMapper;
    4. }

    private SysUserPhMapper sysUserPhMapper;

    1. public void setSysUserPhMapper(SysUserPhMapper sysUserPhMapper) {
    2.     this.sysUserPhMapper = sysUserPhMapper;
    3. }
