How to add the static resources in Spring-boot by annotation? - spring

Question

Besides the pre-determined folders (such as /static/), is there any way to configure Spring Boot (not by XML) to specify the locations of static resources?
For example, starting from this guide, we add another image file, test1.jpg, as our static resource.
Here is the final directory structure:
└── src
└── main
└── java
└── hello
└── Application.java
└── GreetingController.java
└── resources
└── templates
└── greeting.html
└── assets
└── img
└── test1.jpg
We did not change any java code from this guide , but only add one additional line in greeting.html :
<img src="test1.jpg" />
Nevertheless, our greeting.html still cannot find test1.jpg.
Could someone give us some suggestions?
Thanks!!

You can add a #Bean of type WebMvcConfigurerAdapter and set the paths yourself, e.g.
#Override
public void addResourceHandlers(ResourceHandlerRegistry registry) {
registry.addResourceHandler("/**")
.addResourceLocations("classpath:/assets/img";
}
Why not just use the defaults though?
