Custom Live Templates for Java

These are my custom IntelliJ IDEA Live Templates for Java that i'm currently using.

I thought some of them might be helpful for others so i shared them. If you got other cool custom Java live templates which you want to share, feel free to contribute!

Export and Import

All these custom live templates are placed in a custom group. According to sharing live templates I've selected only the live templates and created an export. You can import these settings if you want to get all these templates. Furthermore I've added the templates config file from the IDEA settings. Copy this file to your IDEA settings directory and you are ready to go.

If you just want to add a single live template you can also create it manually.

Java

The live templates are all applicable in Java classes.

            .get("")
            .contentType(org.springframework.http.MediaType.APPLICATION_JSON);

    mockMvc.perform(request)
            .andExpect(org.springframework.test.web.servlet.result.MockMvcResultMatchers.status().isOk())
            .andExpect(org.springframework.test.web.servlet.result.MockMvcResultMatchers.content().contentType(org.springframework.http.MediaType.APPLICATION_JSON))
